摘要
为了治理毕节-都格高速公路K141左侧含煤地层高路堑失稳边坡,以工程地质条件为背景,根据野外勘察分析及位移监测孔曲线,概括边坡失稳破坏三大特征;结合边坡剩余下滑力稳定性验算分析,对边坡进行坡面排水及支挡设计。经过监测,该路堑边坡未见进一步滑动的趋势。
To design the management measures for high cutting slope with coal strata in Bijie-Dugehighway, the geological engineering conditions is taken as the background . The iield geology investigation and displacement curves are combined to conclude the 3 characteristics of overall displacement, mud drum and cracking development gap. Two aspects of designs including drainage and retaining are designed based on slope stability calculation and expert opinion . The cutting slope with coal strata isstable since the measures are constructed .
