Prz. Geol., 69: 884–898; doi: 10.7306/2021.50 A b s t r a c t. The Renaissance Pomeranian Dukes’Castle in Szczecin was built in the late 16 th century in place of older buildings. At that time, the construction, and in particular the foundation of buildings on non-diagenized sediments, was more of an art than a science, since soil mechanics was being born only in the 18 th and 19 th centuries. However, the experience and intuition of old building masters also allowed for the construction of monumental structures that could survive hundreds or thousands of years. Their walls looked solid, so there was no fear of making further renovations and rebuilding in the following centuries. Meanwhile, in 2017, the complex of columns supporting the ceilings of the three-story rooms and the basement in the northern wing of the castle collapsed underground. It happened around 430 years after the completion of construction. The article discusses the results of various types of geotechnical tests, the purpose of which was to determine the causes of the catastrophe. Thanks to the research, a complex of underground tunnels made mostly during World War II, but also previously suspected, was discovered and largely documented. The article summarizes the actual arrangements and describes geological and historical conditions regarding the course and causes of the Castle’s construction disaster in Szczecin. The knowledge resulting from these studies and analyses makes us approach with great caution any interference in the existing static system of seem-ingly powerful and indestructible historic buildings.","PeriodicalId":35787,"journal":{"name":"Przeglad Geologiczny","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47127687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evaluation of the chemical aggressiveness of shallow ground - water for the area of Wrocław was performed in accordance with the Polish Standard (PN-EN 206+A1:2016-12). This standard requires determination of pH and concentration of ammonium, magnesium, sulphate and aggres sive carbon dioxide in water. The research was carried out on 96 ground - water samples collected in the period March–May 2021 from Holocene, Pleistocene and Neogene deposits. The results show that 58% of shallow groundwater in Wrocław was aggressive towards concrete and steel. The slight (XA1), moderate (XA2) and high (XA3) aggressiveness was charac - teristic for 32%, 23% and 3% of the analysed waters, respectively. The significant classification factors were the concentrations of aggressive carbon dioxide, sulphate ions and, less significant, pH. The presence of magnesium and ammonium ions in groundwater did not have any classification significance because of low concentrations. The occurrence of aggressive groundwater is associated with the environment of river sediments, mainly of Holocene and Pleistocene age. Groundwater beneath till and clay formations, mainly of Pleistocene age, and of anthropogenic banks and dumps shows significantly lower aggressiveness. Aggressiveness of groundwater sampled from the aquifer covered by Neogene clay deposit is not demonstrated. The aggressiveness of Wrocław groundwater shows a mosaic space character resulting from the geological structure of the city’s subsurface formations and is probably also related to the form of land development. The most aggressive ones were associated with green, agricultural and liquidated municipal waste dump areas.","PeriodicalId":35787,"journal":{"name":"Przeglad Geologiczny","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71111064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The loess subsoil constitutes over 50% of the Lublin area and determines the geotechnical conditions of the western side of the River Bystrzyca. The paper discusses the geological structure of this part of Lublin and presents an analysis of the results of field research carried out by the author. The research methodology and the method of deriving parameters for the loess subsoil are also proposed. The Lublin loesses were divided into three main facies groups: aeolian (typical loess), aeolian-diluvial and aeolian-alluvial. The basis for the division and parametric characteristics of individual facies were mainly in-situ tests: CPT/CPTU static soundings, DMT/SDMT flat dilatometer tests and PMT Menard pressuremeter tests. The collected data allowed characterizing each of the facies groups and developing a synthetic geological cross-section representing the geological structure of the western part of Lublin. The number of analysed tests allowed stating that the data from CPT/CPTU static soundings are representative for Lublin. Data from DMT/SDMT tests can be considered representative, but further research is needed to refine them and, for example, to separate them by facies. Data from pressuremeter tests should be treated as preliminary. The analyses show that the most common facies in Lublin is silty aeolian one called typical loess, which, according to the author, constitutes approximately 75–80%, and their parameters are of key importance for the design of buildings. The remaining facies groups are about 8–15% for aeolian-diluvial loess and 8–10% for aeolian alluvial loess. Typical loesses are macroscopically homogeneous, but their varying stiffness is reflected in in-situ tests. The basic research method for loess subsoil should be CPT/CPTU static soundings, while the most representative parameter for geotechnical layers is the cone resistance qc. Details of the geological structure and parameters should be performed with DMT, SDMT and PMT tests, as well as laboratory tests, the necessary scope of which can be determined after the development of the subsoil model from the results of CPT tests.","PeriodicalId":35787,"journal":{"name":"Przeglad Geologiczny","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49494788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
