The actual uncovered rock conditions after the excavation show that a series of the optimal designs are correct 对晚秋初冬趾板混凝土采取有效的养护保温措施和施工质量控制，减少了混凝土裂缝发生的可能性。
This paper analyzes on the reasons why the cracks occur on factory concrete road , and advances some measures for controlling the concrete cracks 分析了厂区道路混凝土裂缝产生的原因,提出了控制混凝土裂缝的措施。
It was showed that under the transverse tension , high stress concentration and even concrete cracks would appear on the oblique webs of the model 研究表明，在张拉横向预应力钢束以后，主梁边箱斜腹板中部会出现高拉应力区以及混凝土裂缝。
During the on - site experiment for full - scale segmental model of the girder , stress and cracks of the side - boxes were surveyed 进行标准梁段足尺模型试验，观测试验模型横向预应力钢束张拉后，主梁边箱测点的应变，以及模型表面混凝土裂缝的情况。
And then cracking mechanism of concrete of hydraulic structures such as piers is studied thoroughly , measures of crack prevention in such structures are suggested . g 据此对水工墩墙结构混凝土裂缝成因作了较深入的研究，提出了避免类似结构产生裂缝的工程措施。
Using the system approach to prediction and control concrete crack is very necessary , which possesses important realistic significance and the technological economic significance 用系统方法对混凝土裂缝预测与控制进行研究是很有必要的，具有重要的现实意义和技术经济意义。
2 . having built model of predicting and controlling concrete crack , and using visual basic 6 . 0 languages and matlab program a software of predicting and controlling crack . 3 建立了用灰色系统和神经网络预测和控制混凝土裂缝的模型，并应用visualbasic6 . 0语言和matlab进行了裂缝预测与控制软件的编程。
