岩溶场地勘察质量问题及处理优化方案探讨

Discussion on the Survey Quality Problems of Karst Sites and Their Treatment Optimization Scheme

作为世界上最大的岩溶分布区之一,我国越来越多的工程项目需建造在岩溶地基上。基于岩溶地基的复杂性和不确定性,勘察设计人员须重点关注岩溶场地的勘察工作,以掌握岩溶的形态分布和发育规律等,提高勘察质量。基于广西某岩溶地基勘察中经常遇到的问题,深度分析了影响钻探效果的主要因素,剖析了岩溶地区提高钻探质量的优化措施,对于精准掌握和评价岩溶场地的适用性和稳定性,以及探求岩溶场地地基处理方法具有一定的实践意义。

As one of the largest karst distribution areas in the world,more and more engineering projects in China need to be built on karst foundations.Based on the complexity and uncertainty of karst foundations,survey designers need to pay attention to the exploration of karst sites to master the morphological distribution and development laws of karst and improve survey quality.Based on the problems often encountered in the exploration of a karst foundation in Guangxi,this paper deeply analyzes the main factors affecting drilling results,and analyzes optimization measures for improving drilling quality in karst areas,which is of practical significance to accurately grasp and evaluate the applicability and stability of karst sites and explore the foundation treatment method of karst sites.
