Experimental device and experimental method for soil arching effect between T-shaped piles
The invention discloses a T-shaped pile inter-pile soil arching effect experimental device which comprises a model box and a fixed soil layer arranged in the model box, T-shaped piles are fixed to the fixed soil layer, a loading device is fixed to the inner wall of the model box and connected with a bulldozing plate, the space between the T-shaped piles and the bulldozing plate is filled with a soil body, a soil pressure meter is arranged in the soil body, and strain gauges are pasted to the T-shaped piles. The experimental method comprises the steps that the T-shaped pile is fixed in the model box, the model box is filled with soil, the soil pressure gauge is buried, the loading device applies horizontal thrust load to the soil through the bulldozing plate, and the normal soil pressure of the midspan section of the anti-slide pile and the soil pressure behind the T-shaped pile are monitored. The designed experimental device is simple, easy to install and arrange, easy to operate and capable of being repeatedly operated, the landslide thrust borne by the support pile under the real condition is simulated through the loading device, the strain gauge is used for detecting the tensile strain of the loaded section, and the soil pressure gauge is used for detecting the pressure in the soil body.
本发明公开了T形桩桩间土拱作用实验装置，包括模型箱和模型箱内设有的固定土层，固定土层固定有T形桩，模型箱的内壁固定有加载装置，加载装置连接有推土板，T形桩和推土板之间填充有土体，土体内设有土压力计，T形桩粘贴应变片。其实验方法为模型箱内固定T形桩，填入土体，埋入土压力计，加载装置通过推土板对土体施加水平推力荷载，监测抗滑桩跨中截面的法向土压力和T形桩后的土压力。本发明设计的实验装置简单，容易安装和布置，操作简单可重复操作，通过加载装置模拟真实情况下支护桩受到的滑坡推力，应变片用于检测受荷段的拉应变，土压力计用于检测土体内的压力。
