开封地区湿软路基对路面的影响分析

该文针对开封地区湿软路基含水量高,强度低的状况,采用有限元方法分析了不同土基模量下路面的弯沉、层底拉应力等关键设计指标.计算结果表明,在土基模量较小时,路面控制指标仍然是弯沉;明确了开封地区湿软路基处治应达到的强度标准,可以为该地区路基处治提供技术参考.

Analysis on Influence of West Soft Roadbed on Pavement in Kaifeng Area

Aiming at the status of high water content and low strength of wet soft roadbed in Kaifeng Area,the finite element method is used to analyze the key design indexes of pavement deflection and layer bed tensile stress under the different soil base modulus.The calculation result makes clear that the pavement control index is still deflection when the soil base modulus is smaller.It defines that the treatment of west soft roadbed in Kaifeng Area should satisfy the strength standard,which can be technically referred for the treatment of the roadbed in this area.
