摘要
在软基上修建高速公路时,为保证公路质量一般需要对地基进行加固,为检验加固效果和优化施工,可根据实测数据对沉降发展进行预测,因此选用经验公式法的指数曲线模型,提出利用Origin软件的拟合功能对实测数据进行拟合,计算得到最终沉降、剩余沉降和沉降发展曲线,评价地基处理效果以及指导施工。
The foundation reinforcement is generally required in order to ensure the quality when the highway is constructed on soft foundation. To test the effect of reinforcement and optimize construction, predicting the settlement development according to the measured data is one of the effective methods. Therefore by fitting the measured data through the exponential curve model of empirical formula method in the origin software, the final settlement, the residual settlement and settlement developing eurve could be calculated, and the evaluation of foundation treatment effect and guide the construction could be achieved.
