The cyclic rise and fall of water level in the reservoir will destroy the rock and soil mass of the slope, deterioration its material parameters, cause the uneven settlement of the building foundation, and then cause the structural damage of the upper building.In order to explore the change rule of geotechnical material parameters and the rule and mechanism of structural failure of bank slope buildings under the action of water level cyclic fluctuation. On the basis of obtaining the parameters of soil material after saturated water loss test and based on the finite element interaction analysis method,the slope building model is established by ANSYS.The results indicate that with the ascending of the number of reservoir water lifting and lowering cycles, the differential settlement of the bank slope foundation begins to aggravate. Although the growth rate slows down after 5 cycles, it does not stop, it shows that the mechanical damage caused by reservoir water fluctuation to soil materials of slope is a cumulative process and continue to increase the uneven settlement of the superstructures. The maximum horizontal displacement of prefabricated buildings increases by 2.3 times under the action of reservoir water lifting.

岩土材料参数变化对建筑物的影响

水库中水位的周期性上升和下降将破坏斜坡的岩土质，破坏其材料参数，导致建筑物基础沉降不均匀，进而导致上部建筑物的结构破坏。探索了在水位循环波动的作用下岩土材料参数的变化规律以及岸坡建筑物结构破坏的规律和机理。在获得饱和失水试验后的土壤材料参数的基础上，基于有限元相互作用分析方法，利用ANSYS软件建立了边坡建设模型。研究结果表明，随着水库提水降水次数的增加周期，岸坡基础的差异沉降开始加剧。尽管增长速度在5个周期后变慢，但并没有停止，这表明由储层水波动对边坡土壤材料造成的机械破坏是一个累积过程，并继续增加上部结构的不均匀沉降。在水库抬水的作用下，预制建筑物的最大水平位移增加了2.3倍。
