摘要:
总结了现有差异沉降控制指标的研究成果,在容许路面纵坡坡差0.4%的基础上,研究过渡段路面纵坡坡差与地基差异沉降的关系,建立了软土地基过渡段差异沉降的计算模型,应用PLAXIS有限元软件进行计算,结合数值计算结果探讨了过渡段差异沉降与过渡段的路堤填筑高度、模量的关系,分析得到不同路堤高度时过渡段的路面纵坡坡差与地基差异沉降的关系式,提出软土地基过渡段的差异沉降控制标准.经与江苏省连盐高速公路过渡段实测沉降资料的对比表明,计算差异沉降控制指标是合理的、可靠的,对高速公路软土地基路段修筑过渡段具有实用价值.
Abstract:
The current controlling criteria of tolerable differential settlements were analyzed and summarized. Based on the researches of the tolerable difference of longitudinal slope 0.4%, the relationship between the difference of longitudinal slope of road surface and differential settlement of the ground was studied. The calculation models of transition sections were set up and calculated with PLAXIS finite element software. The calculation results have been used to analyze the relationship between the differential settlement and the height and modulus of the embankment. Concerned equation is gained by analyzing and the controlling criteria of tolerable differential settlements are put forward according to different heights of embankments. Compared with the field survey results of Lian-Yan highway in Jiangsu Province, these controlling criteria of tolerable differential settlements are reasonable, and have practical value on the construction of pavement over soft soil foundation.
