加锚断续节理岩体力学特性的研究及其应用

按应变等效假设及自洽理论建立了加锚断续节理岩体在复杂应力状态 本构关系及其损伤演化方程，并将其应用于三同道峡船闸高边坡稳定性分析中。重点分析了边坡节理尖端产和 生裂纹的可能性及演化长度和用锚固手段减少节理损伤演化区和边坡变形量的效果。

MECHANICAL CHARACTER OF ANCHORING DISCONTINUOUS JOINT ROCK MASS AND ITS APPLICATION

Based on the hypothesis of equivalent strain energy, the constitutive relation of anchoring discontinuous joint rock mass under the state of complex stress and damage evolution equation are established, and applies it to the stability analysis of high slopes of Three Gorges Flight Lock. It puts the emphasis on the analysis of the possibility and the evolution length of subcracks developed in the joint tips of the slopes during the excavation process of the flight lock, and also discusses the effects to reduce the damage evolution zones of joints and deformation quantity of slope with the aid of anchorage. Calculated result shows that obvious reinforcement effect of bolts on jointed rock mass and the surrounding rock mass damage evoluting process can be better reflected by the calculation model proposed.
