摘要
黄土滑坡灾害影响范围广、危害大、治理难。以甘肃天水黄土滑坡为背景,采用现场调查与取土室内实验分析的方法 ,研究了滑坡灾害的发生机理;定性地分析了强降雨以及地震对黄土结构性构度的影响,分析了含水率对边坡稳定的关系,并通过试验揭示了滑坡土的物理性质和静力特性;结合原状土、重塑土和饱和土的无侧限抗压强度试验,采用由原状土和重塑土的无侧限抗压强度比较来反映土的结构可稳性,由饱和土与原状土的无侧限抗压强度比较来反映土结构可变性。
The disaster of loess landslide has a characteristics of wide range,great harm and difficult to control.Taking Tianshui landslide as the background, through field investigation and laboratory analysis of the sampling method,study the occurrence mechanism of landslide disaster; qualitative analysis of heavy rainfall and earthquake structure effects of loess, analyzed the relationship of water content on the slope stability, and reveals the physical properties and static properties of landslide soil through the test; by unconfined compressive strength test to undisturbed soil and remolded soil and saturated soil,analysized the undisturbed and remolded soil unconfined compressive strength compared to reflect the soil structure stability, the saturated soil and undisturbed soil unconfined compressive strength compared to reflect the variability of soil structure.
