Model test discrimination method for arching effect of soil between piles
The invention discloses a model test discrimination method for the arching effect of soil between piles, which can utilize the soil pressure distribution rule measured by pressure sensors mounted in soil bodies at different distances between two adjacent piles, and combine with the apparent shape formed by fine sand layers with different colors laid on the surface of a model soil body after being stressed and displaced, so that the arching effect of the soil between the piles can be discriminated. The soil pressure characteristics and the apparent shape are comprehensively researched and judged, and if the difference between the two judgment results is larger than the center distance of the two piles, it is judged that the result is invalid; otherwise, the judgment result of the pressure box is taken as the criterion. Therefore, the effect of improving the identification reliability is achieved.
本发明公开了一种桩间土成拱效应的模型试验判别方法，可以利用安装在两根相邻桩之间不同远近土体中的压力传感器所测出的土压力分布规律，并同时结合在模型土体表面铺设不同颜色的细沙层在受力变位后所形成的表观形状，将土压力特征与表观形状两者进行综合研判，若两者判别结果相差大于两桩中心距时，则判为无效；反之则以压力盒判别结果为准。从而达到提高判识可靠性的效果。
