| 摘 要： | 随着公路建设速度的加快和发展,高等级公路建设已在我省逐步扩展修建。勘察设计周期正逐步缩短,设计质量要求更加严格,对于桥涵设计的地基基础承载力要求也更高。以往地基承载力依靠工程地质勘察资料及规范、规程有关经验数据确定,但有些数据不单是综合地质地层试验数据及钻探资料的地层原位测试能直接反映的,而是要通过仔细分析地质条件和基础类型及承载力的各种影响因素来确定。本文就是结合公路桥涵所涉及到的有关因素,论述地基承载力在设计中的几种确定意见和方法。

| Abstract: | Along with road construction speed quickening, high grade road is gradually built in our province. Period of reconnaissance and design is shortened. Requirement to Design qualityis stricter. Bearing weight on groundwork of Road Bridge in bridge design is stricter too. But some data from geology and sratum testing and stratum plaee testing can not direcdy be worked out. It will be defined by analysis of geology condition, groundwork type and Factors working on groundwork of road bridge bearing weight. This paper states briefly some opinion and method in bridge design on groundwork bearing weight. |
