Application Research Of Soft Foundation Treatment By Sand-filled Bags In Breakwater

Applying sand-filled bags combined plastic drainage consolidating breakwater soft foundation, this is one of the usual foundation treatments in lately several years. In fields, we can often see foundation settlement is too large, settlement velocity is too quick during the applying load periods. Here whether savageness can still keep stabilization is a question needed to research. Aimed at this question, the paper discusses the connection between foundation deformation and stabilization. The paper introduces Biot consolidation theory, predigests foundation model, then simulates field construction conditions, last accounts the displacements and stress of the foundation, the results inosculates measured results well. By field measured data, the author explores control index of soft foundation reinforcement by sand-filled bags combined plastic drainage, and advises reticence to relax settlement control index in similar engineering. At last, combined engineering case, the paper reasons that sand-filled bags have marked effect in control evening settlement and asymmetry settlement.Slope stabilization is chief control condition in foundation issue. The paper imports limit equilibrium method, simulates field condition, calculates the slope stabilization during construction period, and makes analysis of computer results. For not consider sand-filled bags reinforcement function in computation, the author references research fruits in soft foundation by textile reinforcement and engineering experiences, discusses the function and effect of reinforcement by sand-filled bags, points that reinforcement by sand-filled bags can increase the soil's performance of resisting slippery, thereby resolves the doubt in field, provided experience for similar engineering.The paper analyses the course of foundation consolidation and stabilization, pointed that the application of sand-filled bags in engineering makes good winning, and has preferable value for application and popularization. The widely use ofsanu-filled bags in engineering, would bring well economy and society benefit.
