摘要
Abstract
During the construction of large scale water and soil combined load preloading foundation treatment,the additional stress of preloading load diffuses and causes varying degrees of attenuation in the water bag gap,resulting in underloaded pre-compression in the gap area,which will affect the effectiveness of foundation reinforcement treatment.This article proposes a method to compensate for the attenuated additional stress by adding compensating load in the surrounding range of the water bag gap.It also provides a chart showing the relationship between the water bag gap spacing,the thickness of the loaded soil,and the compensating load under different water bag water injection heights.The accuracy of the calculation of the compensating load in the water bag gap is further verified through numerical simulation analysis and practical engineering applications,as well as the applicability of the"compensating load value chart".关键词
