摘要
土洞是昆明新机场的主要工程地质问题之一。通过地质测绘、高密度电法和钻探手段,探测出工程区土洞132个,其中有部分已出现塌陷现象。论文对土洞的分布规律及其成因机制进行了分析,结果表明,场地总体稳定,适宜机场建设。
Soil cave is one of the main geological problems in Kunming new airport project.Through geological survey,high-density electric method and drilling measures,132 soil caves are detected in working area,some of which have been collapsed.This paper analyzes the distribution rule and cause mechanism of soil cave.It is shown that the field is generally stable,proper for airport construction.
