摘要
运用钻探、物探等综合勘察的方法查明镇胜高速公路K71+460～K71+550岩溶路基的下伏大型溶洞的规模、发育特征,应用FLAC2D数值分析,对敞口的溶洞顶板进行了稳定性分析评价。并通过深层位移监测,证明桥台基础在施工及运营期内是稳定的。
The stabilities of the accumulations are analyzed by means of drilling,geophysical exploration more than highway k71＋460 ~ k71 ＋550 karst steamroller leveled out the large karst down and growing characteristics,with a numerical analysis FLA2D to karst of top a stability analysis.and deep displacement monitoring,based on the construction and operation abutment period is stable.
