摘要
Abstract
In order to investigate the interaction problems between the underground structure and the rich water porous rock a kind of material similar to the porous medium solid-liquid coupling material was developed according to similarity theory of modeling simulation.The material was mixed and pressed from coarse sand.cement pervious concrete intensifier and wakr by certain ratio.Proportioning experiments were carried out based on the orthogonal experiment design principle.Then small model samples were produced to obtain parameters such as the uniaxial compressive strength the permeability coefficient, the bulk density and the elastic modulus and Poisson's ratio.The effects of different ingredients were studied; so the proportions of ingredient were varied for the different needs in physical simulations.The mechanical behaviours of these materials are stable, and not only meet the requirements of large models, but also suitable for large physical experiment on structure and wall rock destruction.Therefore, the simulation experiment material is feasible for risk assessment of underground structure in rich water conditions.关键词
