| 摘 要： | 在软土地区修建高速公路，如果不根据实际情况修建并处理路基，往往会发生路基失稳或过量沉陷问题，导致公路路面破坏甚至不能正常使用。结合邢衡高速公路勘察设计，针对不同工程部位的软土分布规律和特征，设计一套综合处治软土路基的方案措施，并制定了路基沉降和位移观测要求，可为类似软基处理设计提供一定的参考。

| Abstract: | Expressway construction in soft soil area usually brings about roadbed instability and excessive subsidence if its subgrade doesn＇t buih and processed based on practical situations, and it will result in the failure of pavement and can not be utilized normally. Based on the geotechnical investigation and de- sign of Xing-Heng Expressway, this paper designs a set of comprehensive treatment measures for soft soil roadbed aiming at soft soil distribution and characteristics of different engineering parts. Finally, this pa- per makes the observation requirements for roadbed settlement and displacement which could provide ref- erences for other similar treatments of soft soils. |
