广东山区高速公路挖方边坡常见病害及防治策略

广东省山区高速公路发展迅速,但诸多挖方边坡在修建过程中就产生了不同程度的病害。这些病害产生的原因包括气候、地质条件和人为因素,给施工工期、造价及安全管理造成较大影响。鉴于塌方病害在广东地区山区高速公路挖方边坡中较为常见,根据破坏方式及影响范围的深度将其划分为浅层溜塌、浅层滑塌和深层滑塌(滑坡)。结合工程建设经验,提出了山区路堑边坡的防治策略,可为类似工程的设计、施工提供借鉴。

Common Diseases and Prevention Strategy for Cut Slopes of Mountainous Expresswaysin Guangdong Province

Following the rapid development of mountainous expressways in Guangdong Province,a lot of cut slope e diseases have been encountered during the construction.The causes of these diseases include climate,geological conditions and human being factors,which have great impact on the construction period,cost and safety management.In view of common occurrence of collapse disease of cut slope in mountainous area in Guangdong,in this study,according to the failure mode and the depth of the influence range,it has been divided into shallow collapse,shallow landslide and deep slump(landslide).Based on the experience of engineering construction in Guangdong,in this paper,the control strategy for mountainous cut slope has been put forward,which could provide references for the design and construction of similar works.
