Design earth pressure and development of settlements at integral bridges

在所申请的转让项目中，将对现有的整体桥梁设计方法进行检查。基本面基础是在多特蒙德市的一座集成桥上进行的广泛测量，在那里DEGES具有投资者的职能。测量的一部分是土压力作为循环次数的函数的分布。此外，建筑物和邻近填充物的变形作为其温度的函数来确定。利用1136岩土工程课题组建立的改进应力应变关系的数值模型，将计算结果与整体桥的实际设计方法进行了比较。如有必要，对实际规则进行修订。

Within the applied transfer project the existing design approaches for integral bridges will be checked. Fundamental basis are extensive measurements at an integral bridge in the city of Dortmund, where the DEGES has the function of the investor. Part of the measurements is the distribution of the earth pressure as a function of the number of cycles. Furthermore, the deformations of the building and the adjacent refill are determined as a function of its temperature. By a numerical model using improved stress strain relations developed within the research group FOR 1136 Geotech the results of the calculations are compared with the actual design approach for integral bridges. If necessary the actual rules are revised.
