摘要
在研究分析软土地区道路填浜路段工程病害及其成因机理的基础上,揭示了病害的根本原因是道路填浜区域与邻接区域之间路基的“不协调变形”;采用有限元分析方法,研究了路面结构对路基不协调变形的力学响应,建立了控制路基不协调变形的指标和标准;从设计思想、设计依据、设计指标和设计标准等方面,系统建立了基于不协调变形控制的河浜处理设计方法,为今后相关工程提供了技术支持和决策依据.
Based on analyzing the mechanism of diseases of the river and creek treatment section in road engineering in soft ground,it is found that the uncoordinated deformation of the subgrade between the section of river and creek soil treatment and the adjoining region is the essential reason that results in the diseases of the road. Through the finite element method,the surface's mechanics response to the uncoordinated deformation of subgrade is studied,and its control index and standard are also established. Further more,the design theory of the river and creek treatment in road engineering based on the control of uncoordinated deformation is developed,including its design idea,design basis,design index and design standard etc,which offers the support of technology and the principle of decision-making in future correlative engineering.
