摘要
针对高速公路路桥过渡段沉降问题为研究对象,以彭湖高速公路K52+830周通湾大桥过渡段为典型工点开展现场沉降观测。通过沉降计算和理论分析表明,应用指数曲线和双曲线法能较好地反映地基沉降变形规律,可提高工后沉降的预测精度。
For the settlement of expressway road-bridge transition section,site settlement of K52 ＋ 830 Zhoutongwan Bridge transition section of Pengze-Hukou Expressway is observed.Through settlement calculation and theoretical analysis,it is indicated that index curve and hyperbolic method can better reflect the rule of foundation settlement and deformation to improve predicted precision of post-construction settlement.
