| 摘 要： | 针对现行工程设计和数值分析中土的静止侧压力系数K0大多依经验确定并取定值的缺陷,对非饱和含浅层气砂土的K0取值问题开展系统的室内K0固结试验研究。结果表明,含气砂土K0值并非常数,砂土的含水率和密实度均对其有影响;其值随含水率的增大而增大,随密实度的增加而减小,密实度相对于含水率对K0的影响更为显著;工程设计中取松散饱和状态下砂土的K0值是偏于保守和安全的。

| Abstract: | Aiming at the defects that the lateral pressure coefficient K0 is mostly assumed to be constant by engineering experience in practice and in numerical analysis,systemic tests of K0 consolidation on the shallow gassy sand to identify and obtain its value of K0 were carried out. Results show that K0 of the unsaturated gassy sand is not fixed value,and soil structure,moisture content and density all affect it. Its value increases with the rising of moisture content and decreases with the increase of density. T... |
