摘要 在建筑物沉降小的一侧边缘布设相对密集的钻孔排,分期分批地在钻孔适当深度处陶出适量的软弱地基土,使地基应力在局部范围内得到解除或转移,促使软土向该侧移动,迫使该侧沉降,而对另一侧的地基土则不使产生扰动效应,从而达到纠偏扶正的目的。本文通过一个带有普遍性的纠偏工程实例,介绍应力解除法的工作思路、方案选择原则以及应力解除法纠偏全过程。对已倾建筑物的纠偏有一定的参考价值。 The soil stress relieving method is used to correct the inclination of hazardous building, in which one minor subsidence side of the building is bored with relative concentrated holes. Then the soil of foundation in the holes is picked out step by step,so as to relieve or transfer foundation stress in the relevant area, to prompt soft soil in the side to flow away, to force it to settle, and not to disturb the soil of foundation in the other side. As a result, the loaded center of gravity of the building is adjusted by loading in minor subsidence side. Taking one representative case as an example, the paper introduces our ideas, the principles of program and the processes of stress relieving method. The results show that it has some refer enable significance for rectifying deviated constructions.
