高边坡设计与加固问题讨论

DISCUSSION ON THE DESIGN AND REINFORCEMENT OF HIGH SLOPE

摘要: 在高边坡调查、勘探和稳定性评价中,应认识高边坡变形的类型、性质、机制、范围和规模,划分出稳定、基本稳定、稳定性差和不稳定级别.在高边坡设计施工中应按一定的设计思想、技术路线、基本原则和方法指导高边坡的设计施工.高边坡加固工程目前广泛采用预应力锚索框架(地梁、墩)、预应力锚索桩、普通抗滑桩和挡土墙等,应根据实际条件选用.高边坡设计尚无规范可循.如何正确认识高边坡的特性,合理地进行勘察、评价、设计和加固,作者提出了自己的意见和建议,与同行专家讨论.

Abstract: The survey and stability evaluation for high slopes should be concerned about the types, properties, mechanism, scope and scales of slope deformations. The stability grades of high slope may be divided into stable, basically stable, less stable and unstable states. The design and construction of high slopes should be guided by certain designing thought, technique routine, basic principle and methods. The high slopes at present are reinforced with frames, beams, slippery stakes and block walls according to actual conditions. So for, there is not any norm in the design of high slope to follow. The authors put forward some suggestions about the survey, evaluation and design for high slopes.
