Abstract

Experimental research of weak bases reinforced by vertical soil-cement elements are discribed in this article. Tray research ofweak clay bases and bases with percent of reinforcement from 2,1% to 7,1% under strip stamp were conduct. As a result ofthe experiment settlements for each of soil base models were obtained. Characteristic curves of the influence of the reinforcement percentage on the bearing capacity, deformability are given, character of settlements of the investigated soil massin time at step-increasing loading are shown. It was found that depending on the percentage of reinforcement the critical pressures increased linearly and the values of settlement at critical pressures were determined increased with the base reinforcement percentage. Empirical dependencies were obtained to determine the critical pressures depending on the percentage ofreinforcement for the investigated soil conditions. In conclusion, the effectiveness of reinforcing the base of the strip foundations by vertical soil-cement elements was proved.

条形戳记下水泥土单元加固土基应变状态的盘状研究

本文介绍了竖向水泥土单元加固软弱地基的试验研究。对条形印花条件下的弱粘土基和配筋率为2.1% ~ 7.1%的基础进行了托盘试验研究。通过试验得到了不同地基模型的沉降量。给出了配筋率对承载力、变形能力影响的特征曲线，并给出了加筋率随时间的变化规律。结果表明，随配筋率的增加，临界压力呈线性增加，临界压力下的沉降值随配筋率的增加而增加。获得经验依赖关系，以确定根据所调查的土壤条件下的加固百分比的临界压力。综上所述，证明了竖向水泥土单元加固条形基础基底的有效性。
