摘要:
为进一步研究秸秆排水体对疏浚淤泥固结效果的影响,依托念四河西段整治工程,分别开展双层水平秸秆排水体真空预压与双层水平塑料排水板真空预压固结疏浚淤泥的现场试验研究,对比分析两种处理方式下疏浚淤泥的土中真空度、地表沉降、十字板剪切强度、含水率等差异。结果表明:两种排水体处理后的土体沉降量相差较小,且经秸秆排水体处理后的土体含水率略低。说明秸秆排水体具有更好的防淤堵特性,且秸秆排水体处理疏浚淤泥场地用时短,有利于节约工期,经济效益显著,对同类工程有一定参考价值。
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.
