湿陷性黄土地区岩土工程勘察中存在的问题及解决措施

Problems and Solutions in Geotechnical Engineering Surveying at Collapsible Loess Area

在对湿陷性黄土地区进行工程勘察的时候,须查明土层的成分、湿陷系数、湿陷起始压力、湿陷等级及类型等性质;同时结合建筑物的特点、设计要求和周边环境,对地基进行评价,并对工程提出经济合理的地基处理建议。不过,在现场勘察工作中,也存在不少困难,因此,本文针对目前我国工程地质勘察中出现的一些常见问题作了研究探讨,希望对工作实际进行借鉴和参照。

When conducting engineering surveying at collapsible loess area,it is necessary to find out the soil layer composition,collapsing coefficient,initial collapsing pressure,collapsing grade and type,and other properties.At the same time,combined with the characteristics of the building,design requirements and surrounding environment,the foundation is evaluated,and the economic and reasonable foundation treatment suggestions are put forward for the project.However,there are also many difficulties in the field surveying work,so this paper studies and discusses some common problems in the current engineering geological survey in China,hoping to provide reference for the actual work.
