In order to increase the service performance of the well cover, the manufacturer usually improves its bearing capacity in the production of the resin well cover, so as to increase its firmness. However, there are still some factors that will affect the bearing capacity of the well cover, so in order to better avoid it, next let’s understand its factors.

1. The influence of the shape of the shaft cover foundation: when calculating the bearing capacity of the foundation with the theoretical formula of the upper limit load, the strip foundation is considered, and the influence of the bearing capacity of the foundation with different shapes should be considered for the non strip foundation;

2. The influence of load inclination and eccentricity: when calculating the bearing capacity of the shaft cover on the foundation with the theoretical formula, it is considered according to the load at the middle center, but the inclined load eccentricity of the load has an influence on the bearing capacity of the foundation;

3. Influence of the shear strength of the overburden: the higher the shear strength of the overburden above the base, the higher the bearing capacity of the foundation is obviously. Therefore, the size of foundation pit excavation and the quality of construction backfill have an impact on the bearing capacity of the foundation;

4. Influence of the underlying layer: determine the design value of the bearing capacity of the foundation bearing layer, and make a specific analysis and check calculation of the influence of the underlying layer;

5. In addition, there are the effects of base inclination and ground inclination: the compressibility of foundation soil and the proportion of test bottom plate to actual foundation size. Considering the influence of the adjacent foundation of the shaft cover, the influence of the loading rate and the influence of the interaction between the foundation and the superstructure, etc.

As an important performance index of the well cover, the bearing capacity affects the quality of the well cover. Therefore, when installing and using the resin well cover, we need to test its bearing capacity, and we can try to avoid or take measures to reduce the consequences when finding the influencing factors
