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。
In the construction of expressways in soft soil areas, if the subgrade is not constructed and handled according to the actual conditions, the subgrade instability or excessive subsidence often occurs, resulting in the destruction of the road surface or even the normal use. Combined with the investigation and design of Xing-Heng Expressway, aiming at the distribution laws and characteristics of soft soil in different engineering sites, a set of plan and measures for comprehensive treatment of soft soil subgrade are designed and the subgrade settlement and displacement observation requirements are formulated, which can provide similar soft-soil treatment design Certain reference.
