摘要
目前,岩溶地区地基处理设计没有统一的规范或标准可以借鉴。本文根据机场自身特点,通过评判隐伏岩溶的埋藏深度、顶板安全厚度及顶板洞径比等三种主要因素,介绍了一种目前机场常用的岩溶地基处理评价方法,并结合贵州某机场岩溶地基处理设计情况,对场区隐伏岩溶进行评判并提出处理措施,为类似工程提供一些参考和借鉴。
At the present time,there are not the uniform standards and specifications for Karst foundation design.The article introduces a common Karst foundation judgement method in airport engineering,which goes through judging the three main factors of underground Karst caves： burial depth,safe thickness of roof,and roof-critical dimension ratio,and as well the Karst treatments on the Karst foundation design of the airport project in Guiahou province,which provides some reference and guidance to the similar projects.
