吹填坝的原位监测和有限元分析

In-situ Inspection and Finite Element Analysis of Dredger Fill Dam

通过对吹填坝体和地基的孔隙水压力、垂直沉降和水平变形的原位监测分析，控制泥浆吹填速度及施工质量，保证了在淤泥质软土地基中吹填坝的施工安全。用非线性有限元分析坝体地基的应力应变规律与原位监测成果相吻合。原位监测分析结果表明此类软土中吹填法筑坝是可行的，坝体是安全的。

For the dredger fill dam, by means of analysis of in-situ inspection data of pore water pressures.vertical settlements and horizontal deformations, the dredger speed of mud and construction quality are controlled to ensure onstruction safety of the dredger fill dam on the ground base of soft soil of sludge. The stress--strain laws of the dam ground base calculated by non-linear finite element analysis, coinside with the insitu inspection results. The analytic results of the in-situ inspection data show that the dam construction by dredger fill method is practical, and the dam body is safe.
