| Abstract: | In highway bridge construction, there are some problems of controlling and appraising con crete strength when using the method combining statistic with non statistic. Aiming at this, a method to control and assess segmental concrete strength is put forward, which is suitable to the statistic method of construction operation work. Furthermore, the control index Sn is increased to the method of control and appraisal of seg mental strength , and the numerical indexes in JTJ 071 - 98 specification are modified in conjunction with ap plication in Jingzhou Yangtze River Highway Bridge engineering. |
