关于变电工程溶洞和土洞的探测与处理

A View on Exploration and Treatment Method of The Limestone Cave and Soil Cave

岩溶洞隙及其伴生的土洞是覆盖型岩溶地区的常见不良地质现象,它对建筑物基础的稳定性危害极大。在土洞和溶洞分布区兴建变电站等电力设施时,探明溶洞、土洞的分布,采取合理的有效措施对溶洞、土洞进行处理尤为重要,结合某220kV变电站所处地层中土洞和溶洞的成因、探测及处理方法进行全面介绍,为今后类似工程的处理提供借鉴。

Limestone cave and soil cave are the characteristic geological phenomenon of limestone regions, and those caves may bring serious trouble to the stability of building＇s foundation. It is necessary to explore the cave＇s distributing and adopt effective measures to deal with those caves in limestone regions, where transformer substation will be built. The paper overall discusses the genesis, exploration method, and treatment method of the soil cave and limestone cave in the region where one 220kv substation will be built. It can be used as a reference to similar engineering.
