摘要:
以某地工程弃土消纳场中新设的河道底泥堆场为研究对象，采用室内试验及数值模拟的方式，依据固化河道底泥的龄期特性，对不同坡比下的固化河道底泥堆填过程中的稳定性进行分析，得出以下结论：25%水泥与25%石膏复配为最优固化剂，固化河道底泥的安全系数与堆填高度及起坡坡度成正比，相同高度及坡度下，不考虑强度随龄期变化效应的堆体更易失稳；河道底泥固化后可进行即时堆高，若采用分层堆高的方式，堆高作业速度控制在7d/m，以1∶3.5的坡比起坡施工，固化底泥的强度随龄期变化效应可以得到充分发挥，还可兼顾施工安全性及经济性。
Abstract:
Taking the newly built river sediment storage yard at a construction spoil disposal site in a certain area as the research object, this study adopted laboratory tests and numerical simulation methods to analyze the stability of solidified river sediment during the filling process under different slope ratios, based on the age dependent characteristics of solidified river sediment. The following conclusions were drawn: a composite curing agent consisting of 25% cement and 25% gypsum was determined as the optimal formulation. The safety factor of solidified river sediment was positively correlated with the filling height and slope gradient; under the same height and slope conditions, the fill mass ignoring the strength age dependent effect was more prone to instability. Solidified river sediment could be subjected to immediate elevated filling. If the layered filling method was adopted, controlling the filling operation rate at 7 days per meter and conducting slope construction with a gradient of 1∶3.5 would not only give full play to the strength age dependent effect of solidified sediment, but also balance construction safety and economic efficiency.
