Embodiment 1
[0050] Such as figure 1 As shown, embodiment 1 provides a method for treating the uneven settlement of iron tower legs in the subsidence area, and the method comprises the following steps:
[0051] S1: Based on the tower leg with the smallest settlement, calculate the settlement of the four bases of the iron tower.
[0052]In step S1, use the Leica TS9R500 total station to measure the foundation settlement of the four independent foundations located at the foot of the iron tower in the subsidence area. The measured settlements of the four tower foundations of ABCD are a, b, c, d. The relative settlement method is adopted in the finite element simulation calculation, and the tower leg with the smallest settlement is taken as the reference point, that is, assuming that the settlement of leg A is the smallest value among the four tower legs, it is assumed that the settlement of leg A is 0, and the settlement of leg B, C, and D is assumed to be 0. The settlements of the legs are ...
Embodiment 2
[0087] Such as figure 1 As shown, Example 2 also provides another treatment method for the uneven settlement of iron tower legs in the subsidence area. On the basis of the method described in Example 1, step S7 is added, which calculates the optimal reinforcement structure by dichotomy Material selection and size.
[0088] 1) For steel structure reinforcement, adjust the size of the foundation reinforcement structure through the section shape and size settings in the section option in ansys. The overall stress level of the tower body is less than the design strength of the bar as the standard. If this standard is met, it is called Satisfy the stress condition.
[0089] First select a smaller size a for trial calculation, and then choose a larger size b for trial calculation. If the large size meets the conditions, the overall stress level of the tower body is less than the design strength of the bar, and the small size does not meet the conditions, then use two points The id...
