摘要:
深厚淤土地基加固是软基处理中经常遇到的难题,本研究针对淮河入海水道二期工程堤防加固中存在长距离、大面积深厚淤土地基的特点,提出微劈裂多层面真空预压技术并在入海水道北堤进行工程性试验,试验过程中通过对真空度、地面沉降、十字板不排水抗剪强度等指标的监测以及对监测数据的分析,表明微劈裂多层面真空预压技术加固深厚淤土地基效果显著,土体有效加固范围更大,在排水板打设范围内的土体均能得到不同程度地有效加固。
Abstract:
Reinforcement of deep silting soil foundation is a difficult problem in soft foundation treatment.In view of the characteristics of long-distance and large-area deep silting soil foundation in embankment reinforcement of flood way of Huaihe River flowing into sea Phase II Project, a micro split multi-layer vacuum preloading technology was proposed and an engineering test was carried out on the north dike.Through the monitoring of the vacuum degree, ground subsidence, vane-undrained shear strength of the cross plate and the analysis of monitoring data during the test showed that the micro split multi-layer vacuum preloading technology was effective in strengthening deep silt soil foundation, and the effective reinforcement range of soil was larger.The soil in the range of drainage plates could be effectively strengthened to varying degrees.
