地基基础遇地下防空洞处理方法探析

The Analysis of the Approach to the Foundation Met with the Underground Air-raid Shelter

防空洞是城市建设过程中经常遇到的一种情况,合理的处理方案需要结合地下防空洞被覆结构、地质条件、防空洞的现状以及建筑物基底压力等情况等综合考虑。本文结合工程实践经验,从探明防空洞具体情况,洞体强度验算,介绍了卸荷拱计算原理及盖板抬梁法在防空洞加固中的应用。

Combined the covering structures, geological conditions and situations of the underground air--raid shelter and the basal pressure of the building, the reasonable treatment options of the underground air raid shelter, which is usually met in the city building, should be considered comprehensively. Based on the practical engineering experience, the paper introduces the calculation principle for unloading arch and the application of cover lift beam method on the underground air--raid shelter from proving the specific situations and checking the strength of the shelter.
