谈几种常见特殊性岩土场地勘察时应注意的问题

Discussion on geotechnical site investigation problems of several special rock and soil

岩土工程勘察质量直接影响工程的安全性、经济性等重大问题,对后期工程建设具有重大的指导意义[1]。为提高勘察工作质量,从填土、湿陷性黄土、膨胀性土等几种工程中常见的特殊性岩土出发,总结了上述几类特殊土场地岩土工程勘察时的关键因素和应该注意的问题,并结合工程实例,从建筑物类别划分、建筑范围跨越不同地貌单元和人类工程活动等方面做了一些有益的讨论,对实际勘察工作具有一定的参考意义。

The quality of geotechnical investigation directly affects major issues such as engineering safety,economy and so on,which is of great guiding significance for the later stage of engineering construction. In order to improve the quality of investigation work,the key factors and problems that should be paid attention to are summed up from the geotechnical investigation of the several special soil sites,which are common geotechnical projects,such as fill,collapsible loess and expansive soil. Some useful discussions have been made on the classification of buildings,building range across different topographic features unit and human engineering activities,these summaries and discussions have certain reference significance for actual investigation work.
