摘要

在软土堆积层的土地复垦工程中,为了减少未来静、活荷载作用下的沉降,往往需要对地基进行改良。在海相粘土沉积较厚的情况下,通常需要使用预制垂直排水沟来加速粘土的固结过程。在此类工程中,必须确定改善程度,以确定土壤是否达到所需的固结程度,然后再去除附加物。这种分析可以通过从仪器安装之日起连续监测地面行为的观测方法来进行。本文以新加坡樟宜东填海工程为例,介绍了岩土工程仪器在施工控制中的应用。本工程采用的现场仪器有沉降板、深度沉降计、土压力计、气动压力表、电压力表、水柱等。

Instrumentation at Changi land reclamation project, Singapore
Ground improvement is often required in land reclamation projects on soft soil deposits to reduce future settlement under the projected future dead and live loads. In the case of thick deposits of marine clay, it is often necessary to accelerate the consolidation process of the clay using prefabricated vertical drains. In such projects, the degree of improvement has to be ascertained to confirm whether the soil has achieved the required degree of consolidation before the removal of surcharge. This analysis can be carried out by means of observational methods for which the ground behaviour is continuously monitored from the date of instrument installation. This paper provides a case study of the applications of geotechnical instrumentation for construction control in the Changi East reclamation project in the Republic of Singapore. Field instruments adopted in this project included settlement plates, deep settlement gauges, earth pressure cells, pneumatic piezometers, electric piezometers and water standpi...

期刊介绍: The objectives of the Association shall be the promotion of co-operation among geotechnical societies in SE Asia; and the assistance to member societies who have limited number of members. Now there is only one combined web titled: AGSSEA-SEAGS. SEAGS & AGSSEA encourage the submission of scholarly and practice-oriented articles to its journal. The journal is published quarterly. Both sponsors of the journal, the Southeast Asian Geotechnical Society and the Association of Geotechnical Societies in Southeast Asia, promote the ideals and goals of the International Society of Soil Mechanics and Geotechhnical Engineering in fostering communications, developing insights and enabling the advancement of the geotechnical engineering discipline.
