摘要
通过对珠江三角洲淤泥类软土的试验研究成果,结合具体工程,对淤泥类土的物理力学指标进行统计和分析,探讨不同围压大小、剪应变水平等对土的动弹模量、剪切模量和阻尼比的影响。为了解珠江三角洲地区软土的物理、力学特性,选择最优的软基处理方案,建立实用的设计计算模型,采取完善的施工技术措施有至关重要的作用。
The physical mechanics indexes of sludge have been statistically calculated and analyzed in combination with concrete project through lots of experiments results of sludge in Pearl River Delta. The authors discussed the effect of different confining pressure, shearing strain level etah on dynamic elastic modulus, shear modulus and damping ratio of sludge. The study is very vital for getting the Physical and mechanical properties of soft soil, selecting the optimized treatment for soft foundation, establishing practical calculation model and adopting preferable construction technology.
