The Basic Primciples of Self-bearing Protect of Foundation Soil
-
摘要: 本文从地下工程围岩收敛约束曲线出发，在总结现代围岩支护理论的基础上，导出了基坑土体支护位移曲线，阐述了基坑土体自承支护的基本原理。这种支护体系不再把土体仅当成荷载，而是将其看成一个有机的整体，支护的目的不是去”支撑”不稳定土体，而是以充分发挥土体自支承能力为出发点。Abstract: This paper proposes the protect-displacement curve of foundation soil based on the covergence constraint curle of the surrounding rock in underground engineering and the modern protect theory. This protect system dose not take soil as only load to protect structure, but take soil and structure as an organic whole. The aim of protect is not to'prop' the unstable soil, but to fully develop the self-bearing capacity of soil.
