工程活动对桂林市西城区岩溶塌陷的影响分析

摘要

分析了西城区认为塌陷的特征，深入分析抽取地下水、人工加荷、振动以及基坑开挖等工程活动对岩溶塌陷的影响。指出不合理抽取地下水是该区人为塌陷的主要原因，最后探导了减少人为塌陷灾害产生的方法及措施。%The characteres of the artificial collapses are discussed in this paper, and the influence of the artificial engineering load, vibration or excavation ect. on the artificial collapse is deeply analyzed.It is pointed out that unreasonable pumping of groundwater is the main reason for causing the artificial collapse.The measures artificial collapses are also discussed.
