影响树脂复合井盖承载能力因素

来源:http://www.kpp647.com添加时间:2016-12-05 16:58:01

1、荷载倾斜与偏心的影响:在用理论公式计算地基承载力时,均是按中心受荷考虑的,但荷载的倾斜荷偏心对地基承载力是有影响的。

1, load tilt and eccentric effect: in the theoretical formula to calculate the foundation bearing capacity, are in the center of the load to consider, but the load of inclined load eccentric foundation bearing capacity is affected.

2、此外对树脂井盖还有基底倾斜和地面倾斜的影响:地基土压缩性和试验底板与实际基础尺寸比例的影响,相邻基础的影响,加荷速率的影响和地基与上部结构共同作用的影响等。

2, in addition to the resin covers and basal ground tilt tilt and the influence size ratio and compression test plate and the actual foundation soil, influence of adjacent foundation, the influence of loading rate and foundation and superstructure interaction effect etc。。

3、下卧层的影响:确定地基持力层的承载力设计值,应对下卧层的影响作具体的分析和验算。

3, the impact of the underlying layer: to determine the bearing capacity of the foundation bearing capacity design, to respond to the impact of the underlying layer for concrete analysis and checking.

4、基础形状的影响:在用极限荷载理论公式计算地基承载力时是按条形基础考虑的,对于非条形基础应考虑形状不同地基承载的影响。

4, based on the shape of the impact: the ultimate load theory is used to calculate the bearing capacity of the foundation is to consider the strip foundation, for non strip foundation should consider the impact of different shapes of the foundation.

5、覆盖层抗剪强度的影响:基底以上覆盖层抗剪强度越高,地基承载力显然越高,因而基坑开挖的大小和施工回填质量的好坏对地基承载力有影响。

5, the influence of the shear strength of the covering: the higher the shear strength of the basal layer, the higher the bearing capacity of the foundation, the size of the foundation pit excavation and the quality of the construction backfill have an influence on the bearing capacity of the foundation.

相信看了本文的介绍后,对这方面也会有自己的一番认识,以后针对山东球墨铸铁井盖http://www.kpp647.com必须要严格等问题也能很好的解决。

Believe that the introduction of this article, will also have a new understanding of the future in Shandong, ductile iron manhole cover http://www。jnwszy。com must be strict and other issues also can be a good solution。
