摘要
基桩孔底溶洞发育程度将严重影响建筑构造物主体结构的安全,因此在岩溶发育区进行基桩施工时需对孔底持力层的岩溶发育情况进行探测.通过采用声呐法在岩溶发育区孔底进行实际运用探测,并与结果进行验证,综合评价此方法在岩溶发育区的适用性.
The development degree of karst cave at the bottom of foundation pile will seriously affect the safety of the main structure of the building.Therefore,it is necessary to detect the karst development of the bearing layer at the bottom of foundation pile in the karst development area.In this paper,sonar method was used to detect the hole bottom in karst development area,and the results were verified to comprehensively evaluate the applica-bility of this method in karst development area.
