| 摘 要： | 类软土是一种特殊意义上的软土,它与一般沉积软土比较,在形成原因、分布范围、物质组成等其他特性上有区别;由其构成的类软土滑坡则具有普通滑坡不具有的特征。以京珠高速粤南段K108类滑坡为例,介绍了滑坡的地层岩性、构造特征、水文地质特征;应用位移监测方法查明滑坡有五层滑动带,滑面成近于圆弧形的勺形,并对滑坡的产生原因及滑动过程进行了分析,得出降雨和边坡的开挖是导致滑坡的直接诱因。

| Abstract: | Quasi-soft soil is one special kind of soft clay with different characteristics in its formation,distribution,physical composition from other common sediments.Therefore,landslide occurred in the quasi-soft soil should have its own characteristics.The strata lithology,geologic structure and hydrogeologic features of the landslide are demonstrated by a case study at the K108 quasi-soft soil landslide along the Beijing-Zhuhai highway.Five slip surfaces and shape of slip bed of the landslide are identified by displacement monitoring.It was concluded that rainfall and slope excavation are two primary causes for landslide. |
