The Study Of Control And Prediction Of Highway Settlement By The Method Of Settlement Rate

The method of drained consolidation becomes more wide-ranging in application of soft foundation treatment as the developments of express highway more fast. The problems of construction which needed to solve and research aroused one by one, and the problems will long-time exist in construction of express highway, but have not been solved through and through. The article was based on the existing studying of foundation treatment, according to the real monitoring data, through the calculation of the theory in the article and the analysis of FFM, the article profoundly studys the characteristic of foundation settlement and the methods of calculation in The method of drained consolidation. The article tends that the method of settlement rate which to calculate the settlement of soft foundation own obvious predominance. Achievement of the article as following:1 Based on the engineering experience, the article decrypts the development of elemental theory of soft foundation treating, like the existing condition and history of the elemental theory of consolidation and settlement ,compareing and analysis of ordinary calculation and prediction of settlement.2 Based on the Asaoka method, the article deduce the method of settlement rate (MSR). also, the article curve settlement rate ,and analysize the method of settlement rate (MSR) by the curve.3 The article spreads the method of settlement rate to calculation and prediction of settlement in complicated condition,and further spread the applicability of the MSR..the arcticle also analysize the merits and demerits in complicated condition4 The article introduces the calculations of settlement,the prediction of rest settlement, loading rate,unloading time,and systematicly introduce the apply of the MSR.5 According to the real data, FFM analysis and the formulas of the article, the article analyses the settlement of some typical section,calculate the rest settlement and prepared settlement.Also, and evaluates the reinforce effectiveness. Further approve that the MSR has fine effectiveness.
