| 摘 要： | 多元复合地基的沉降计算依赖于其复合模量的取值.目前多元复合地基复合模量计算均未考虑桩对桩间土的侧向挤密作用,因而其沉降计算结果与实际值相差较大.而考虑桩体与桩间土的侧向挤压作用,依据线弹性变形理论,推求的多元复合地基的复合模量公式应用于工程实例,结果表明,该方法是合理可行的,并且存在着参数易于确定、方法简便、机理清楚的特点.

| Abstract: | The composite modulus is important for the settlement analysis.Now the calculation of the composite modulus do not think over the action of side extrusion between pile bodies and earth among piles,so there is a big difference between the result of calculation and practical settlement.Considering the action of side extrusion between pile bodies and soil among piles,the composite modulus formula for the multi-composite ground base is deduced and obtained,in terms of linear elastic deformation theory,and the f... |
