摘要
根据相似原理和岩石结构面直剪试验的要求,选择高强水泥砂浆作为模拟材料。通过严格控制原材料,优选配合比,掺加硅粉和高效减水剂等措施,可以制备出强度达到72Mpa的匀质水泥砂浆来模拟岩石材料,从而解决了大型岩石结构面直剪试验取样困难的问题。
Cement mortar of high strength is selected as simulation material on the basis of resembling theory and demanding of direct shear test of rock structural plane.Uniform cement mortar of above 72Mpa can be manufactured by taking a series measures such as raw material quality control,mixing ratio optimization,using siliceous powder and superplasticizer.Thus the Sampling difficulty of direct shear test of mass rock structural plane is solved.
