某高速公路桥梁中长期养护规划研究

Study on Mix Ratio Design of Cement Stabilized Sand Gravel Pile in Frozen Soil Area

合理的养护规划对于延长桥梁结构的服役年限,降低全寿命周期养护成本具有十分重要的意义。基于此,论文通过对某高速公路桥梁历年检测数据分析及桥梁技术状况评价,建立了桥梁结构技术状况衰变模型,并根据每年检测数据进行调整,提高其预测准确性,依此制订该桥中长期养护规划方案。

Reasonable maintenance planning is of great significance for extending the service life of bridge structures and reducing the maintenance costs throughout their entire life cycle.Based on this,this article analyzes the inspection data of a certain highway bridge over the years and evaluates the bridge technical condition,establishes a bridge structure technical condition decay model,and adjusts it based on annual inspection data to improve its prediction accuracy,Based on this,develop a medium-and long-term maintenance plan for the bridge.
