摘要: 为了研究金佛山中厚覆盖层上修建溢洪道的可行性,对覆盖层采用邓肯-张模型,计算分析了系数K取最值情况下溢洪道纵剖面与横剖面在修筑与泄 水运行时的应力与变形。研究表明:溢洪道大小主应力均未超出规范值,16-16断面在泄水运行时地基横槽向向坡外的位移较大,覆盖层地基邓肯-张模型 参数中系数K增大将会使溢洪道结构的大小主应力、伸缩缝的变位、地基的沉降与横槽向水平位移的减小。故应充分论证边坡在泄水时边坡的稳定性,并 建议对覆盖层地基采取适当的加固措施。

Abstract: In order to study the feasibility of Jinfo mountain spillway building on the thick overburden, Duncan-Chang model was used on the cover layer, and the stress and deformation of cross-section and longitudinal section of spillway in the construction and operation of the sluice were calculated and analyzed, in the case of the tangent elastic modulus coefficient K with the maximum and minimum value. The results show that the max and min principal stress of spillway don’t exceed the standard value. The displacement at the outer slope of foundation transverse groove in the 16-16 section is larger during the operation of the sluice. If the tangent elastic modulus coefficient K increases, the max and min principal stress of spillway structure, the deflection of spillway expansion joint, the settlement of the foundation and the horizontal displacement of transverse groove will decrease. Therefore, the slope stability should be fully demonstrated during the operation of the sluice, and it is suggested the appropriate reinforcement measures should be taken for the thick overburden.
