| 摘 要： | 将水平加筋垫层视为一弹性薄板,地基土体简化为Winkler弹性地基模型,考虑水平加筋体的影响,由功的互等定理推导出双向增强体复合地基沉降计算式.该式综合反映了水平加筋垫层抗弯刚度、桩间距、地基土体基床系数、上部荷载等因素对复合地基沉降的影响.完成了一组"刚性桩+土工格栅"复合地基载荷试验,用文中方法计算其逐级加载下的沉...

| Abstract: | The horizontal reinforced cushion was regarded as an elastic sheet and the soil foundation as a Winkler elastic foundation model.Considering the influence of the horizontal reinforced cushion,the formula of the settlement of double direction reinforced composite foundation was deduced by using the reciprocal-work theorem.This formula takes the following influence factors into account: the flexural rigidity,the pile spacing,the foundation modulus of the soil,the upper loads and so on.The loading test of ther... |
