Two Problem Study of Optimization Design in Foundation
In order to optimize the design of foundation pit support in specific areas of soil conditions, the equivalent angle of internal friction was put forward to instead of internal friction and internal cohesion based on the theory and practical engineering experience. Then the optimization design of calculating parameter for soil pressure was realized. At the same time, the optimization of protecting piles design become reality that based on the circular section piles convert to the rectangular section piles through equal stiffness according to its characteristics. Through the application of the optimal design method in a practical engineering, the result proved that the method improves the anti-overturning ability of the soil and saves the engineering cost of the piles.
