| 摘 要： | 仁宗海水电站坝基第7层灰色淤泥质壤土,呈可塑-软塑状,力学性质较差,承载力和变形模量低,不能满足基础承载、变形和坝坡稳定要求:地震烈度7度时为地震液化土。设计采用振冲碎石桩加固处理。试桩试验满足设计要求,为后期方案设计、施工提供了有效、可靠的参数。

| Abstract: | The 7th layer of the dam base of Renzonghai Hydropower Station is of grey mucky-soil,in a state of plastic to soft plastic and with poor mechanical properties,low load-carrying capacity and low deformation modulus.It cannot meet the requirements of load-carrying capacity of foundation,deformation and the stability of dam slope.It becomes liquefied soil when the earthquake intensity reaches 7.The detritus column vibroflotation is adopted to reinforce its foundation.The tests provide available credible data for the subsequent design and construction. |
