【摘要】 在回顾土的临界状态理论发展的基础上,将土的稳定状态理论应用于海底滑坡研究。依据这一理论,将浙江东部沿海海底滑坡分为整体性滑坡和破碎性滑坡两类。这一分类方法的优点是它可以反映滑坡土休的工程特性以及破坏机制,一般来说,处于翦胀状态的土易形成破碎性滑坡,处在剪缩状态的土易形成整体性滑坡。在此基础上,还以岙山20万吨级原汕码头滑坡为实例,分析了土体失稳的机制和过程。更多还原

【Abstract】 Based on the overview of soil steady-state theory development, detailed analyses are carried out on the subaqueous landslides. According to soil steady-state theory, the subaqueous landslides in nearshore off Zhejiang Province are classified as nondisintegrative failures and disintegrative failures. The advantages of the classification based on the theory are that it can suggest the soil behavior and mechanism of landslide. At last, trigger factors and mechanisms of a landslide off Aosan 20 tones Crude Oil Dock are analyzed.更多还原
