| 摘 要： | 土工袋可将高含水量的淤泥土装入编织袋封口而重新用于工程实践中,解决淤泥土难处理的问题.通过室内试验研究,验证土工袋可显著提高淤泥土的强度,其极限抗压强度达到普通混凝土的1/10左右.在压缩过程中,袋内土体的凝聚力有所降低,摩擦角有所增大,同时由于编织袋的滤水作用,淤泥土的含水率有所降低.通过沉降固结试验,得到了淤泥土土工袋的沉降过程曲线,并推得了淤泥土土工袋的累计沉降预测公式.

| Abstract: | For treating abundant of mud soil produced by engineering, soilbag technique is introduced to let the mud soil be filled into soilbags and reused into engineering practices. The ultimate compressive strength of the soilbag filled with mud soil is obtained through a series of laboratory tests, which reaches one tenth of compressive strength of ordinary concrete. For the soil in the bag, the cohesion decreases but the internal friction angle increases during the compressing process. While the water content of mud soil reduces due to water filtration of the woven bag. Through consolidation testing, the settlement-time curves are obtained; and then a formula is derived for predicting the total settlement of soilbags filled with mud soil. |
