| 摘 要： | 将复合地基的加固区和下卧层作为一个整体,加固区视为压缩模量为复合模量的天然地基,按天然地基的分层总和法计算复合地基沉降.以竖向荷载作用下Boussinesq应力解和位移解为基础,建立了复合地基沉降量的可靠度分析模型.并结合工程实例对复合地基沉降量的可靠指标的影响因素进行了分析.考虑复合地基变形可靠度分析中,功能函数的高...

| Abstract: | The reinforced area and non-reinforced area of a composite foundation are regarded as a whole,the reinforced area is taken as a natural foundation whose compression modulus equals as a composite modulus;the settlement of the composite foundation is computed by means of the layering summation method of a natural foundation.The models for the reliability analysis on the composite foundation settlement based on the Boussinesq's stress and displacement solution under a vertical concentrated load is established.... |
