Device and method for preventing an underground structure from liquefying and floating
The invention discloses a device and method for preventing an underground structure from liquefying and floating. The device comprises a water collecting tank, wherein the water collecting tank comprises a shell and a water collecting chamber arranged in the shell, the shell is provided with a plurality of water permeable holes, the water collecting chamber is communicated with the outside of the shell through the water permeable holes, a barrier is arranged in any one water permeable hole in a matched mode, in the initial state, the blocking piece prevents water in the soil layer from entering the water collecting cavity from the water permeable holes, and when the soil body is liquefied, the blocking piece is opened and guides the water in the soil layer to enter the water collecting cavity from the water permeable holes. The method is advantaged in that the weight of the underground structure is increased during earthquake liquefaction, meanwhile, effective stress is increased, buoyancy generated by water pressure in soil is reduced, and the underground structure is prevented from floating upwards and being damaged in a liquefied soil layer during an earthquake.
本发明公开了一种防止地下结构液化上浮的装置及方法，所述装置包括集水箱，集水箱包括外壳和设置在外壳内部的集水腔室，所述外壳布设有若干透水孔，透水孔将集水腔室与壳体外部连通，任一透水孔内配合设有阻隔件，初始状态下阻隔件阻止土层中的水从透水孔进入集水腔室，土体液化时阻隔件开通且引导土层中的水从透水孔进入集水腔室。本发明的有益效果是地震液化时增加了地下结构的重量，同时增加有效应力且减少土中水压产生的浮力，防止地下结构在地震时液化土层中的上浮破坏。
