Optimum Design for Cross-section of Gravity Retaining Wall Based on lstOpt Software

In order to solve the complicated calculating indexes and difficulty to draw the best results of the retaining walls design. The smallest cross-section objective function of the gravity retaining wall is established which can meet the stability and the requirements of the bearing capacity of foundation, get the non-linear mathematical optimization model and a domes-tic mathematical optimization software lstOpt is used to solve. This method avoids the cumbersome process of the trial calculation and a reasonable cross-section of economic size could get, and has been successfully used in Zhong Wu gas line along the protection of hydraulic engineering.
