摘要
分析了处于不稳定边坡地段半填半开挖类路基的破坏机理 ,指出了边坡地下水向路基的侧向渗流是诱发该类路基灾害最活跃、最关键的因素 ,阐明了在对该类路基排水系统设计的同时进行边坡排水系统布设 ,可以有效降低和防止路基水毁灾害的发生。以重庆某高速公路滑移边坡路段的路基排水系统设计为例 ,对此做出了验证。
The damaged mechanism of subgrade with half fill and halt cut at instable slope was analyzed. It is pointed out that the side seepage is a key factor to destroy the subgrade performance. So the roadbed drainage system should be designed to prevent the water damage of this kind of subgrade. An example design was presented.
