摘要
基于岩溶发育的基本规律出发,指出变形和水害是岩溶路基病害的主要形式,路堤不均匀沉降和路基失稳是岩溶路基病害的具体表现.根据路段石芽、漏斗、洼地、溶洞、溶隙、岩溶泉等多种岩溶形态并存的特征,并考虑岩溶形态的尺度效应,遵循疏导、跨越、加固、堵塞的方法进行预防和处理原则,提出X1合同段岩溶路基的具体处理措施.
Based on the developping disciplinarian of karst, it is pointed out that distortion and water damage are two basic types of Subgrade damage, and asymmetric settlement and stability lose of subgrade are the material reflections of karst subgrade damage. According to the karstic characters of X1 where clint, funnel, billabong, dissolved cavern and karstic spring existe at the same time,considering the scale effects of karstic configuration,abiding by the preventting and disposing principles by dredging and leading, spanning,reinforcing and jamming,the disposal material measures for karst subgrade of X1 section are put forward.
