摘要: 針對前坪水庫工程砂礫石黏土心墻壩的特點,結合地質、設計和相關試驗資料,采用南水雙屈服面本構模型,開展三維流固耦合計算分析,計算考慮施工、蓄水時間效應以及運行期長期變形時間效應等,模擬前坪水庫工程壩體的填筑過程、施工后至蓄水前、蓄水過程以及運行期的壩體應力變形分布規律和工作性態。研究發現:考慮流固耦合作用時,砂礫石黏土心墻壩最大應力、應變都較耦合前大;壩體在施工期最大沉降率為1.25%,運行期累計最大沉降率為1.36%;施工期最大水平位移為17.7 cm,運行期累計最大水平位移為35.2 cm。

Abstract: Aiming at the characteristics of sandy gravel dam with clay core of Qianping Reservoir, combined with geology, design and related test data and Nanshui double yield surface constitutive model, this paper conducted the calculation and analysis on threedimensional fluidsolid coupling. The calculation considered construction and the effects of storage time and run time deformation and time effect for a long time, before the actual simulation flat reservoir dam in the actual filling process before and after construction to water storage, water storage process and operating period of dam deformation and stress distribution law and workability. The results show that the maximum stress and strain of sandgravel claycore dam are larger than those before considering fluidsolid coupling. The maximum settlement rate of the dam is 1.25% during the construction period. The cumulative maximum settlement rate during the operation period is 1.36%. The maximum horizontal displacement during the construction period is 17.7 cm and the cumulative maximum horizontal displacement during the operation period is 35.2 cm.
Key words: sandgravel clay core dam; fluidsolid coupling; stressstrain analysis; Qianping Reservoir
