| 摘 要： | 根据拼接路基的变形特点，结合已有的工程实践经验，提出了采用新、老路基横坡的改变量及工后沉降量作为改扩建工程的控制标准。采用此标准，可有效控制通车后的工后沉降量及不均匀沉降，并节约软基处理费用。

| Abstract: | According stitching roadbed deformation characteristics, combining engineering experience, the paper take the change in cross slope of the old and new roadbed and the amount of post-construc- tion settlement as a control standard for expansion project. With this standard, the amount of post- construction settlement and differential settlement can be effectively controlled after the opening, and the treatment cost of soft ground can be reduced. |
