摘　　要：轻骨料混凝土应用于工业与民用建筑可减轻结构自重、节省材料、提高构件运输和吊装效率、减少地基荷载、提高建筑物的抗震性.工程上的构件大多处于正应力与剪应力的共同作用下,因此研究页岩陶粒混凝土在压扭联合作用下的相关性具有重大的理论意义和应用价值.通过试验研究页岩陶粒混凝土在压扭联合作用下的力学性能及破坏形态,得到页岩陶粒混凝土在压扭联合作用下的相关曲线.根据试验数据并利用混凝土强度准则回归出相关曲线.The use of shale ceramisite concrete for construction can decrease weight of construction,save structure material,improve efficiency of element transport and hoisting,decrease the load of foundation and improve the resist ance to earthquake etc.Because many elements of engineering were in state of combined stress es,the character of shale ceramisite concrete under combined stresses must be investigated.The me-chanic character and damage form of shale ceramisite concrete under combined compress-torsion were stud-ied through experimental and theoretical analysis.Meanwhile using test data and concrete criterion regress the related curve by the variable of octahedral stress.The interrelationship curve of shale ceramisite concrete under combined compression-torsion was obtained.The curve can provide the reference for structural designs.
