摘要
悬臂式桩板挡土墙因诸多优点被日益广泛地应用于公路路基支挡工程中,但其支挡高度(即桩的悬臂长度)过大时,结构的承载能力、可靠度和经济性都将劣化。通过对桩板挡土墙的支护抗力、桩顶位移、工程造价与支挡高度关系的定量分析,得到其综合特性曲线,据此提出了公路桩板挡土墙支挡高度的合理区间值。
Due to the benefits of cantilever-type sheet-pile wall,it is applied in the reinforcement of highway subgrades universally in recent years. However,when the retaining height( i. e. the length of pile cantilever) is out of range,deterioration may occur with regard to the carrying capacity,reliability and economy of the structure.According to the quantitative analysis of the relationship among the supporting resistance force,displacement of the top pile,engineering cost and retaining height of the sheet-pile wall,we found out the comprehensive characteristic curve is found. Based on the which,a group of interval values of the rational retaining height of highway sheet-pile wall are proposed.
