Type and Reason Analysis and Research of Design Changes in A Mountainous Area Highway

公路工程项目建设过程中,由于种种原因,经常会遇到设计变更问题,导致项目工程投资增加、建设周期延长,甚至影响项目的通车运营。总结分析设计变更的类型及原因,在前期设计阶段充分合理减少不必要的后期工程变更,对保证项目建设质量和后期运营安全、控制工程造价等,具有十分重要的意义。

Due to various reasons,the design changes are often encountered during the construction of highway,resulting in increased project investment,extended construction period,and even affected the open of the highway. Fully and reasonably reduce unnecessary engineering changes in the early design stage by summarizing and analyzing the types and causes of design changes is very meaningful to ensure highway construction quality and operation safety,and also can effectively control the project cost.
