软基路堤沉降速率与剩余沉降的关系
Relationship between settlement rate and residual settlement of embankment on soft ground
摘要
Abstract
The relationship between settlement rate and residual settlement of embankment was studied on soft ground,expressions of residual settlement and settlement rate were respectively derived from the hyperbolic time-settlement curves, based on which the relational expression of the settlement rate and residual settlement were deduced. The final settlement and residual settlement were deduced according to measured settlement information using hyperbolic method,and the dot graphs of measured settlement rate and corresponding residual settlement,measured settlement rate and residual settlement square were respectively drawn, and the measured settlement information of embankments on soft ground of two expressways were made. The results show that the settlement rate is in direct proportion to residual settlement square. The embankment on soft ground of the two expressways is basically in direct proportion to the residual settlement square, and the settlement rate has polygonal relation with residual settlement.关键词
