摘要
在高速公路建设中,针对影响超孔隙水压力u计算的静水压力h定义的不确定性与实际观测中静水压力增量Δh和荷载增量Δp在量测上存在的问题,提出了解决方法,并通过工程实践,成功地采用了"孔隙水压力监控图解法"以控制加载速率。
In the freeway construction,for the problem of the uncertainty in the definition of the hydrostatic pressure h,which affects the calculation of the excess pore water pressure u,and the measurement problems in the hydrostatic pressure increase Δh and the load increment Δp in the actual observations,solutions are proposed. Through engineering practice,the ＂pore water pressure monitoring and graphic method＂was successfully adopted to control the loading rate.
