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, 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, 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, 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, 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。
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。
