Existing rockfall trajectory models are not suited for this purpose because they do not consider the non‐linear dynamics of rock motion, which is highly dependent on rock size, shape and impact configuration. In this paper, we discuss the application of the new 3D rockfall modelling tool Ramms::Rockfall, which computes rock‐ground interactions using hard‐contact impact mechanics. The model is applied to evaluate the effectiveness of a rockfall bank at the Geobrugg/WSL test site in Walenstadt, Switzerland.","PeriodicalId":170042,"journal":{"name":"Geomechanics and Tunnelling","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125881472","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 main objective of soil conditioning is the reduction of its shear strength to control the counterpressure inside the bulk chamber. In order to preserve the pseudo‐fluid characteristics of the conditioned soil mass, the main concerning para meters are their undrained properties. To characterise the un drained behaviour an adopted watertight direct shear apparatus was used. The purpose of this research is to define a simplified testing procedure for conditioned soil, analysing its feasibility and reliability with resources that can be found at any laboratory or job site. A comparison between the results obtained under dry and conditioned conditions is presented for three different cohesionless soils. The choice of the materials studied has been made in order to cover a wide range within sands grain size.","PeriodicalId":170042,"journal":{"name":"Geomechanics and Tunnelling","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122447484","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 binary granite is relative fresh on the bottom of the walls, but the weathering increases significantly to the natural surface. The bedrock shows an orthogonal joint system enabling the so‐called ”Wollsackverwitterung“. Mapping of the joints followed by a kinematic analysis of the quarry wall by DIPS (Rocscience) indicates the slope failure to be of a planar sliding type on a medium‐steep dipping plane. As the contributing factor for the slide, weathering along the plane has to be considered. Thereby the destruction of rock bridges downgrades the overall shear strength. A stability analysis based on the reconstructed block geometry and the determined shear parameters verifies the instability of the block. For today's situation, the kinematic analysis detects some critical intersections of joints being able to generate slide wedges.","PeriodicalId":170042,"journal":{"name":"Geomechanics and Tunnelling","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122503924","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}

This secondary movement overlies a deep‐seated rock slide. The rates of movement at the surface of the earth‐flow/‐slide were between 1 und 3 cm/a before the implementation of remedial works. Starting from the geotechnical and geomechanical model of the slope, measures were developed, which were intended to reduce the movement. A monitoring system was installed to provide information about the movement and slope water conditions of the earth‐flow/‐slide and the sliding rock mass. In order to estimate the creep behaviour of the earth‐flow/‐slide, the ductility index ILZR was determined from shear tests. A simple flow law was assumed for the estimation of the change of creep rate. Measurements over a period of about 18 months after the first phase of remedial works show rates between 0.5 and 1.2 cm/a. The reduction of the rate of movement is compared with the creep model applied and the viscosity index ILZR to check the validity.","PeriodicalId":170042,"journal":{"name":"Geomechanics and Tunnelling","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124373262","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 Ingelsberg exhibits periodic episodes of instability, prompting major efforts to construct rock fall retention basins and safety nets to mitigate risks associated with future slope failures. As the results of traditional slope monitoring have proved rather ambiguous, continuous real‐time monitoring of the Ingelsberg was performed from March 2013 through July 2014. The monitoring was undertaken with a Ground Based Interferometric Synthetic Aperture Radar (GB‐InSAR). The data set of approximately 130, 000 radar scans represent the first long‐term GB‐InSAR measurements made in Austria, and indicate an episodic pseudo‐sheeting failure process, somewhat analogous to the calving of a glacier front. Furthermore, reasonable time of failure predictions for rock fall events having volumes of only several tens of cubic meters could be made from the data set. The GB‐InSAR monitoring provides significant insight regarding the overall slope behavior, failure tendencies, and associated geotechnical hazards of the Ingelsberg.","PeriodicalId":170042,"journal":{"name":"Geomechanics and Tunnelling","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117511917","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}
