摘要:
为研究尾矿坝的动力抗震特性以及为抗震措施提供理论指导,以四川某尾矿库为例,分析了该尾矿坝在EI Centro地震波、汶川地震波和人工地震波作用下的位移、加速度、液化、安全系数的动力响应特性。采用GDS动三轴仪对该尾矿库的3种典型尾矿进行动力实验,研究结果表明:随着动剪应变幅的增大动剪切模量比逐渐减小,阻尼比逐渐增大;3种尾矿的动压缩弹性模量的倒数与动轴向弹性应变之间的关系为直线关系,在双对数坐标系中,平均有效应力与动剪切弹性模量的关系为直线关系;尾粉质黏土抗液化强度较低,应优化尾矿排放工艺使其尽量沉积到库尾。
Abstract:
In order to study the dynamic seismic behavior of tailings dam and provide theoretical guidance for seismic strengthening measures, taking a tailings pond in Sichuan as an example, the displacement, acceleration, liquefaction and safety factor dynamic response characteristics and displacement of the tailings dam under the action of EI Centro seismic wave, Wenchuan seismic wave and artificial seismic wave were analyzed. The GDS dynamic triaxial apparatus was used to carry out dynamic experiments on three typical tailings of the tailings pond. The results show that: γ>10-2 is the difference between the dynamic shear modulus ratio, the damping ratio and the dynamic shear strain amplitude of different tailings. The demarcation point, the relationship between the reciprocal of the dynamic compression elastic modulus of three kinds of tailings and the dynamic axial elastic strain is a linear relationship. In the double logarithmic coordinate system, the effective consolidation confining pressure and dynamic shear elastic modulus. The relationship is linear; the silty clay has a low liquefaction resistance, and the mine should optimize the tailings discharge process to deposit as much as possible to the tail of the reservoir.
