摘要
结合岩溶地区某建筑物桩基施工灌注混凝土时发生的地面塌陷问题,分析岩溶勘察中常规钻探方法的局限性和管波探测法的优势,提出在岩溶强发育场地宜采用超前钻与管波探测相结合的方法进行岩溶勘察,通过查明岩溶发育情况,为基础设计提供依据,以保证基础施工及上部结构安全。
Based on the ground collapse problem happening during pile foundation concrete grouting in karst area, this paper analyzed the limitation of conventional drilling method and advantage of tube wave detection method during karst exploration, and proposed that composition method of advance drilling and tube detection should be adopted for karst exploration at area with strong karst development. Detection of karst development condition could provide basis for foundation design, to guarantee the safety of foundation and upper structure.
