| 摘 要： | 在公路路网改造工程项目中,常常遇到旧路补强设计,通过工程实例和理论分析,解决旧路补强设计中容易出现的补强层厚度随着老路回弹模量的增大而增厚的现象,即通常所说的"反常现象";结合工程实例,通过优化超高设计,将位于缓和曲线段内结构物不设置在超高缓和段上,给桥梁的设计和施工带来极大的方便。

| Abstract: | The so-called abnormal phenomenon in the design of the strengthening course during the reconstruction of existing roads,i.e. the thickness of the strengthening course becomes larger with the increase in the modulus of resilience of the exsting road,is studied theoretically,and based on the analysis of practical cases,a feasible method for solving the problem is put forward. For the other common problem in highway design,i.e. the influence of superelevation in the much longer transitional zone on the design of certain structures,a practical case is investigated,and it is advanced that through the optimum design of superelevation, the structures appeared in the transitional zone may not be designed in the superelevation run-off,and such design is beneficial to the design and construction of bridges. |
