| 6. | Through the analysis and calculation the conclusion can be made that during the process of the timbering of excavation , the magnitude of soil stress decreases with the increase of the displacement on the base of the still earth pressure , and the earth pressure distribution varies from the triangular distribution of the still earth pressure to other distribution with the displacement of the timbering structure . the thesis introduces the bedding coefficient in the horizontal direction varying with the soil displacement from soil - structure interaction mode , therefore calculation can be made to get more rational calculation result using elastic foundation finite element method which is the same to timbering structure both upwards and under excavation surface
通过分析计算可以得出，在基坑支护过程中，土压力的大小在静止土压力值的基础上随支护结构向坑内侧位移增大而减小；土压力的分布由静止土压力的三角形分布随支护结构位移变化成其它分布；由土-结构共同作用模式引入随土体位移变化的水平向基床系数，使支护结构在开挖面以上部分同以下部分一样，均可采用弹性地基有限元法进行计算，得出更为合理的计算结果。 |
