基础底面 meaning in English
bottom of foundation
foundation base
Examples
- Some results are as follows under the action of vertical load , piles and soils are able to support upper loads , this improving the bear capacity of composite foundation a lot ; changing the character of the pile during transferring the vertical stress , reducing compressive stress under foundation
在垂直荷载作用下，桩、土都可以承担上部荷载作用，进而能大幅度提高复合地基承载力，改变了桩传递轴向应力的特征，减小了基础底面的压力等。 - Abstract : optimum design of individual foundation considering the effect of strength and deformation is discussed in this paper . the optimal mathematical model of determining the bottom surface demention of individual foundation under eccentric load is derived . the optimal solution is decided by method of optimization and the method we select is penalty fonction and complex method . the program of optimum algorithm is comiled and design and drawing of individual foundation is completed . the final results of engineering samples suggest that the cost of material and engineering amount can reduce approximatly 5 % - 6 % . a fair - sized economic efficiency can be received by using optimum method to design foundation
