在固体模型材料研究的基础上,应用固流耦合相似理论,通过大量的配比试验,研制出一种新型的固流耦合相似材料(PSTO),这种材料用砂和滑石粉作为骨料,石蜡作为胶结剂,并配以适量调节剂混合而成.通过大量的室内试验,系统研究不同相似材料配比和装模温度对试件性能的影响规律,得到影响相似材料性质的若干因素.该材料的力学特性与岩石性质相似,且在水的作用下不发生软化,非亲水性良好,可模拟不同渗透性的低强度和中等强度的岩体材料,是一种非常理想的固流耦合相似模拟材料.将该材料应用于隧道涌水模型试验,可有效地揭示了位移、应力、渗压等多场信息的变化规律.

A new similar material(PSTO) for solid-fluid coupling has been developed through hundreds of compounding tests based on the theory of solid-fluid coupling and the experimental study of solid model material. It is mixed with sand,talc powder,paraffin and hydraulic oil. Sand and talc powder are used as aggregated;paraffin is used as a cementing agent;hydraulic oil is used as a regulator. The effect of different mixing ratios and loading temperatures on the properties of the samples has also been studied through large numbers of laboratory tests. The new material is completely non-hydrophilic,thus there is non-occurrence of softening under the action of water. It belongs to brittle materials with a similar nature of rock mass,which can be used to simulate low-strength and medium-strength rock materials with different permeabilities. So it is an ideal similar material for solid-fluid coupling. This material has been used in a tunnel water-inflow model test;and the variation of the multi-field information such as displacement,stress and seepage pressure has been effectively revealed.
