预拱度 meaning in English
pre-camber
Examples
- The results demonstrated that the ann is efficient and the theoretical results fit well with that of forecasting the beam camber in construction
分析表明该方法是有效的，与实测预拱度结果较吻合。 - The bridge has builded by balanced cantilever construction technique . the beam camber of construction is a controlling index of construction quality control . it is nonlinear , and now is not mature forecasting method
该桥采用节段式悬拼施工法，其施工预拱度的控制是关键指标，目前没有一个成熟预测方法。 - In this essay the technique of the structure calculation and error adjustment measures used in bridge construction prefigurative deviation control was researched based on the construction control and monitor project of wuhan caidian han river bridge
本文主要结合蔡甸汉江公路大桥的施工监测监控项目，研究施工预拱度控制的结构计算和误差调整方法。 - The deflection ' s computation is complicacy when considered the agents included concrete creep . so we should compare the calculation results with design date before construction to find the problem . we should continually adjust the elevation date in construction control to reduce the error
考虑徐变后结构的挠度计算是极其复杂的，因为它包含了包括混凝土徐变在内的许多因素，而且即使计算出预拱度，在施工之前也应将计算数据并与设计值比较，从而发现问题。 - Then on the basis of calculating result from the prefigurative deviation control structure calculation , " rational data forecast processing about error adjust in prefigurative deviation control was made by the prefigurative theory of bp neural network and corresponding program and software matlab6 . 1 . at last via the data comparison with the practical survey data draw a conclusion : it is feasible for the construction prefigurative deviation control and error adjust used in pc rigid frame bridges to use the calculation model and program brought forward in this paper
