土质地基在岩溶地区的应用浅析

Analysis of the application of soil texture foundation in karst area

本文通过对岩溶地区进行岩土工程勘察查明岩土体的力学特征,并对岩土体特征进行综合分析评价结合建筑物特点采用粉质粘土作为地基持力层。研究区场地较平坦,粉质粘土具有一定厚度,具有一定承载力,分布较均匀,粉质粘土适宜作为地基持力层。岩溶地区土质地基作为地基持力层的情况较少见,本文就粉质粘土作为地基持力层对场地进行力学性质及地基评价分析,为后续类似地区提供借鉴。

In this paper,the mechanical characteristics of rock and soil were identified by geotechnical investigation of karst area,and comprehensive analysis and evaluation of rock and soil characteristics were carried out,and silty clay was used as the foundation holding layer based on the characteristics of buildings.The site of the study area is relatively flat,the silty clay has a certain thickness,has a certain bearing capacity,and the distribution is relatively uniform,and the silty clay is suitable as a foundation holding layer.In karst areas,soil foundation as a foundation holding layer is rare,and this paper analyzes the mechanical properties and foundation evaluation of the site with silty clay as the foundation holding layer,so as to provide reference for subsequent similar areas.
