基于岩溶发育地区岩土工程勘察及场地稳定性评价

Geotechnical Engineering Investigation and Site Stability Evaluation in the Karst Development Area

在岩溶地区进行岩土工程勘察时为准确获得岩土体物理力学参数,为解决因岩土工程勘察技术不当而导致勘察数据失真的问题。通过对岩溶发育地区进行仔细分析研究,在进行岩土工程勘察前制订与勘察现场相符合的勘察设计方案。根据设计方案进行勘察,当出现新的地质问题时及时调整方案,最大限度地发挥岩土工程勘察技术手段的优越性,最终提供完整且准确的勘察数据。勘察完毕后,对岩溶场地进行稳定性评价,提供可靠的地基承载力和地基持力层,提供地基基础初步建议。

When conducting geotechnical engineering investigations in karst areas,in order to accurately obtain the physical and mechanical parameters of the rock and soil mass and solve the problem of the distortion of survey data caused by improper technology for geotechnical engineering investigations,this paper carefully analyzes and studies karst development areas,and formulates a survey and design scheme that is consistent with the survey site before geotechnical engineering investigations.It carries out investigations according to the design scheme,and adjusts the scheme in time at the emergence of new geological problems,so as to maximize the superiority of technical means for geotechnical engineering surveys and finally provide complete and accurate survey data.After the completion of the survey,it conducts the stability evaluation of the karst site to provide the reliable bearing capacity and bearing layer of the ground,and provide the preliminary suggestions of the ground foundation.
