River foundation pit indoor model test device and test method
The invention relates to a river-near foundation pit indoor model test device and a test method, jacks are arranged on the river-near side and the river-back side of a foundation pit, so that different asymmetric loads are applied to the two sides of the foundation pit, and the deformation characteristic of the foundation pit along with the change of the loads is obtained; a plurality of water outlets with different calibers are arranged, so that diversified regulation and control on the water level descending speed are realized, and a basis is provided for researching a rule of influence of water level descending on stress deformation of a foundation pit soil body; the front pool and the water surrounding pool are arranged on the two sides of the water tank, simulation of water flow in the limited space of the water tank is achieved, the water storage tank and the water pump are arranged between the front pool and the water surrounding pool, water flow circulation is achieved, and the influence of the water flow velocity and water level rising on foundation pit soil deformation can be studied.
本发明涉及一种临河基坑室内模型试验装置及试验方法,通过在基坑的临河侧和背河侧均设置千斤顶,实现了对基坑两侧施加不同的非对称荷载,得到基坑随载荷变化的变形特性;通过设置数个不同口径的出水口,实现了对水位下降速度的多样化调控,为研究水位下降对基坑土体受力变形影响的规律提供了依据;通过在水槽两侧设置前池和围水池,实现了在水槽有限空间内的水流的模拟,并通过在前池和围水池之间设置储水箱和水泵,实现了水流循环,能够研究水流流速和水位上升对基坑土体变形的影响。
