一、引言 在自然界,滑坡是一种常见的灾害地质现象。我国黄河中上游广大地区,超固结土中的滑坡十分发育,严重威胁这一地区铁路、公路和水利等建设事业的发展。 为了认识滑坡规律,有效地防治滑坡,长期以来,人类在与滑坡的斗争中,从彼德森(K·Epctterson)的瑞典园理论到太沙基(K·Terzaghi)的条分理论,从毕肖甫(A·W·Bishop)发展了的条分理论,再到斯开普顿(A·W·Skempton)的残余强度理论,反映了人类发展滑坡理论的进程。然而,以往的这些理论大都把上视为刚塑性体,用极限平
I. INTRODUCTION In nature, landslides are a common disaster and geological phenomenon. In the vast middle and upper reaches of the Yellow River in our country, the landslides in the over-consolidated soil are well developed, seriously threatening the development of railways, highways and water conservancy projects in this area. In order to understand the law of landslide and prevent the landslide effectively, for a long time humankind has been fighting the landslide. From K · Epctterson’s theory of the Swedish park to Terzaghi’s theory of division, The bar theory developed by BW Bishop and the residual strength theory of A.W. Skempton reflect the progression of the theory of human development and landslide. However, most of these theories in the past regard the rigid plastic body as the limit level
