摘要
[目的]岩溶发育地区面临复杂多变的地质问题,文章旨在降低岩溶发育地区工程建设的风险。[方法]文章以粤北某电厂为例,分析比较了弹性波CT和钻孔探测的结果,探讨如何应用弹性波CT结果指导桩基设计,给出了桩基设计的要点。[结果]结果表明:可以利用弹性波CT探测指导超前钻的施工和桩基持力层的判断;桩基设计可通过转换大梁等方法进行优化。[结论]研究成果可为岩溶发育区工程建设提供参考。
[Introduction]Karst development areas face complex and changeable geological problems.This paper aims to reduce the risk of engineering construction in karst development areas.[Method]Taking a power plant in northern Guangdong as an example,this paper analyzed and compared the results of elastic wave CT detection and drilling detection,discussed the how to use elastic wave CT results to guide the pile foundation design,and provided the key points of pile foundation design.[Result]The results show that elastic wave CT detection can be used to guide the construction of advance drilling and the judgment of pile foundation bearing stratum.The pile foundation design can be optimized by means of transfer girder and other methods.[Conclusion]The research results can provide reference for engineering construction in karst development areas.
