岩溶地区对路基的破坏及其处理措施

在岩溶地区，变形和水害是岩溶对路基破坏的主要形式，路堤不均匀沉降和路基失稳是岩溶路基病害的具体表现。故应根据路段漏斗、洼地、溶洞、溶隙、岩溶泉等多种岩溶形态并存的特征，并考虑岩溶的尺度效应，遵循“疏导、跨越、加固、堵塞”的预防和处理原则，提出岩溶路基的具体处理措施。

Destruction of Subgrade and Treatment Measures in Karst Area

In karst area, distortion and water disease are the main forms of the destruction of subgrade caused by karst. Differential settlement of embankment and instability of subgrade are the specific phenomena of subgrade disease in karst area. According to the characteristic that manifold karstic forms exist together such as funnel, billabong, karstic cave, karstic fissure, karstic sping and so on, the scale effect of karst is considered, the principle of ＂leading, spanning, reinforcement, jamruing＂ is followed and applied, and then the specific measures used to treat the subgrade in karst area are proposed.
