摘要

Large particle-size, shallow groundwater level, and large permeate coefficient are the characteristics of gravel stratum, which may results in large ground deformation. Ground deformation depends on several factors. Using the RFPA2D-Flow software exploited by the Center for Rock Instability and Seismic Research of Northeastern University (CRISR), the seepage-stress-deformation coupling rules of soil, which are influenced by different soil distributing, drawdown, enclosure and excavating, were analyzed, and the deformation of gravel in the dynamic balance due to the interaction between seepage and stress is studied.
