某岩溶地区勘察方法及岩土工程评价分析

Exploration Method and Geotechnical Engineering Evaluation Analysis in a Certain Karst Region

在勘察岩溶地区时,由于岩溶在地下的发育具有难以观察的特性,因此如何探清岩溶的发育特征、岩溶的高度及横向发育规模是岩溶地区勘察的难题。文章以遵义某工地为例,介绍了该工地的勘察方法,并采用工程地质调绘、工程测量、钻孔布置及工程地质钻探等手段,清晰地了解到该拟建场地的岩土层分布特征及岩溶发育规模,为该项目的拟建建筑基础埋深、地基承载力及基础形式提供帮助。

When surveying karst areas,due to the difficult to observe characteristics of karst development underground,it is difficult to explore the development characteristics,height,and lateral development scale of karst in karst areas.The article takes a construction site in Zunyi as an example to introduce the survey method of the site,and uses engineering geological mapping,engineering surveying,drilling layout,and engineering geological drilling methods to clearly understand the distribution characteristics of the rock and soil layers and the scale of karst development of the proposed site,providing assistance for the burial depth,bearing capacity,and foundation form of the proposed building foundation of the project.
