ANALYSIS ON MECHANISM OF WATER-INDUCED LANDSLIDES AND MONITORING CONTROL SCHEME ESTABLISHMENT

An important factor affecting the stability of the slope is the fissure water in the rock mass. In this study, taking consideration in the mechanism of fissure water acting on layered rock, the related theory of rock mechanics, fluid mechanics and soil mechanics were used to analyze the stress characteristics of layered rock mass under hydrostatic pressure, water softening dissolution effect on rock mass, fissure filling effective stress, dynamic water scouring with groundwater level. Though these above study of the typical interaction mechanism between water and rock mass, the pregnancy, development, and occurring of water-induced landslides were revealed in order to assess stability of layered slope. Finally, the targeted slope monitoring scheme was formulated and the reasonable reinforcement proposal was given for a targeted specific case. The research results can provide reference for the theory of rock slope instability in the rich water stratum and the treatment measures.
