【摘要】 运用离心模型试验研究河道护岸工程,通过试验掌握挡土墙在完建期、运行期及水位骤降期工况下的工作性态,分析了解不同方案不同工况下挡土墙上的土压力、墙后土体孔隙水压力的变化规律,地基沉降和墙变位、整体稳定性等岩土工程问题,再经过综合分析,可以使设计方案优化到最为经济合理。更多还原

【Abstract】 The geotechnical centrifugal model test was utilized to study the revetment design for the bank of river. Through this test,the working status of retaining wall was found during building- up period,usage period and suddenly reducing water - level period.These geotechnical questions,such as the changing law of earth pressure and hydraulic pressure which act on the retaining wall - back,the settlement of foundation,the deformation and the whole stability of wall under different scheme and working mode,etc.were also analyzed.Synthesizing all relevant factors,it is feasible to make the design scheme optimum and most economic.更多还原
