水平秸秆排水体联合真空预压加固疏浚淤泥现场试验研究
Field experimental study on combined horizontal straw drainage body and vacuum preloading reinforcement for dredging sludge
摘要
Abstract
To further investigate the influence of straw drainage body on the consolidation effect of dredged silt,relying on the remediation project of the western section of Niansi River,field experimental studies on the consolidation of dredged silt by vacuum preloading with double-layer horizontal straw drainage body and vacuum preloading with double-layer horizontal plastic drainage board were carried out respectively.The differences in vacuum degree in soil,surface settlement,vane shear strength,moisture content and other aspects of dredged silt under the two treatment methods were compared and analyzed.The results show that the difference in soil settlement amounts after treatment with the two types of drainage bodies is relatively small,and the moisture content of the soil treated with the straw drainage body is slightly lower.This indicates that the straw drainage body has better anti-clogging characteristics.Moreover,the time taken to treat the dredged silt site with the straw drainage body is shorter,which is conducive to saving the construction period.It has significant economic benefits and has certain reference value for similar projects.关键词
