一、前言许多研究者已注意到某种大型滑坡具有较高的流动性。Scheidegger(1973)、Hsü(1975)、Li(1983)和Okuda(1984)发现滑坡的最大垂直落差(H)与最大水平运动距离(L)之比随滑坡体积的增大而减小。Sassa(1988)根据饱合物不排水加荷的观点解释日本1984年的Ontake堆积层崩坍的高流动性。作为此观点的具体应用,本文介绍了滑坡体积与平均视摩擦角(tan~(-1)H/L)之间的理论关系式,对滑落在冲积层上的滑坡,用快速荷载环剪仪来测定其视摩擦角。
I. INTRODUCTION Many researchers have noticed that a large landslide has high mobility. Scheidegger (1973), Hsü (1975), Li (1983), and Okuda (1984) found that the ratio of the maximum vertical drop (H) to the maximum horizontal distance (L) of a landslide decreases with increasing landslide volume. Sassa (1988) explained the high mobility of Japan’s 1984 Ontake collapse due to undrained loading of the sorbate. As a concrete application of this view, this paper presents the theoretical relationship between the landslide volume and the average apparent friction angle (tan~(-1)H/L). For a landslide that lands on the alluvium, use a fast load-ring shear tester. To determine the apparent friction angle.
