城市高大建筑物的修建有时不可避免地遇到隐伏岩溶地基问题。实践证明,仅以少数钻孔岩芯的抗压强度作为地基承载力的评价依据可能导致严重的工程失误。真正影响地基强度和稳定性的因素是埋藏岩溶面形成的各种临空面、岩体中的溶洞、溶隙、溶蚀带以及基坑开挖过程中抽排水引起的各种城市环境效应。岩溶地基工程地质勘察与评价工作,必须在岩溶专家指导下综合应用物探、钻探、水文地质试验、示踪等技术进行综合研究,为设计提供包括环境效应评价在内的各种依据。岩溶地基处理工作必须把加固、防水、保护环境三个方面的问题统一起来考虑
The construction of tall buildings in cities sometimes inevitably encounter the problem of hidden karst foundations. Practice has proved that only the compressive strength of a few borehole cores is used as the evaluation basis for the bearing capacity of the foundation, which may lead to serious engineering errors. The factors that really affect the strength and stability of the foundation are the various voids formed by the burial karst surface, the caverns in the rock, the gap, the corrosion zone, and various urban environmental effects caused by the drainage during the excavation of the foundation pit. In the karst foundation engineering geological survey and evaluation work, comprehensive research must be conducted under the guidance of karst experts to comprehensively apply techniques such as geophysical exploration, drilling, hydrogeological tests, tracer, etc. to provide various basis for design including environmental impact assessment. The treatment of karst foundations must integrate the three aspects of reinforcement, waterproofing, and environmental protection.
