软弱夹层相似材料配比试验研究

结合软弱夹层的物理力学性质，根据相似原理进行配比试验，研制适用于室内试验的软弱夹层相似材料，使用单因素试验和正交试验相结合的方法进行研究，以因素A(石蜡/(骨料+膨润土))、B(石膏/(骨料+膨润土))和C(骨料/膨润土)为控制因素，以密度、抗压强度和弹性模量作为不同配比的评价指标.单因素试验以石英砂或重晶石粉作为骨料研究材料物理力学性质的变化.正交试验通过因素水平变化分析其敏感度，结果表明密度、抗压强度和弹性模量随因素水平变化规律性明显.

英文摘要:

Combined with physical and mechanical properties of weak intercalation.The proportioning test is conducted according to the principle of similarity.This study aimed to develop an appropriate similar material for weak intercalation which can be used in physical model test in laboratory.The single factor test and orthogonal test is combined to research.Three controlling factors including A(paraffin-aggregate and bentonite)，B(gypsum-aggregate and bentonite)，C(aggregate-bentonite ratio)are chosen to perform the orthogonal tests.A series of tests is carried out to determine the density，compression strength and elasticity modulus of different similar materials.The physical and mechanical properties of similar material which use quartz and barite powder as the aggregate is studied.The sensibilities of three factors level change are analyzed by orthogonal test.The results show that the density，compressive and elasticity vary with the factor level.
