高墩大跨连续刚构渡槽施工监控研究

STUDY ON CONSTRUCTION MONITORING OF CONTINUOUS RIGID AQUEDUCT WITH HIGH PIER AND LONG SPAN

针对黔中地区水利枢纽工程中的大跨度连续刚构渡槽施工监控问题,建立精细化有限元分析模型,模拟徐家湾连续刚构渡槽的施工过程,分析计算了各施工阶段徐家湾渡槽的结构行为。根据分析结果,通过比较各阶段的高程变化和计算值,验证了计算模型和分析方法的正确性,为高墩大跨连续刚构渡槽积累施工经验。

In view of the monitoring of the long-span continuous rigid-frame aqueduct in the Guizhou Water Conservancy project,a detailed finite element analysis model was established to simulate the construction process of Xujiawan continuous rigid-framed aqueduct.This paper analyzed and calculated the structural behavior of Xujiawan aqueduct at various construction stages.Based on the analysis results,the correctness of the calculation model and analysis methods were verified by comparing the elevation changes in different stages and calculated values,accumulating experiences for construction of high pier long-span continuous rigid-framed aqueduct.
