Taking nanpu bridge ( fst bridge ) in chun - an county as an instance, many problems on construction control technique for cfst bridge are discussed in this paper, including : the analysis method of simulating construction phase, construction monitoring technology, calculation of stayed - buckle - cable forces, allotting deadweight of pumping liquid concrete, analysis on the inflection of shrinkage and creep of core concrete in steel tube, analysis on the error in construction control, sensitivity analysis of parameters and parameter identification
本文以淳安縣南浦大橋為背景，對鋼管混凝土拱橋施工控制中的結構分析方法、施工監測技術、斜拉扣索索力計算、泵注混凝土自重荷載的分配、鋼管核心混凝土收縮徐變分析、施工控制誤差分析、參數敏感性分析及參數估計等問題展開研究。 -
The peculiar mechanical character about pumping liquid concrete is discussed. based on the supposition that the ability of transferring hydraulic pressure of liquid concrete is orthotropic and the friction forces exists between concrete and steel tube, the pressure formulas of liquid concrete and the allotting formulas of deadweight are reasoned out. a new method is brought forward for allotting deadweight of liquid concrete during simulation analysis in pumping - core - concrete construction phase, which improves the calculation precision
在探討泵送液態混凝土的特殊的力學性質基礎上，在假定液態混凝土傳遞壓強能力為正交各向異性、混凝土與鋼管壁之間的存在有摩擦力的前提下，推導出液態混凝土壓強公式和自重荷載的分配公式，提出了在進行鋼管內混凝土灌注過程的施工模擬分析時處理液態混凝土自重荷載分配的合理方法，從而提高施工模擬分析的計算精度。
