摘要
以长春市伊通河排水管网改造工程为例,通过现场实测中粗砂地层条件下采用泥水平衡顶管顶进过程中顶进力的变化情况,系统研究了影响顶进力的因素及其变化规律,并对顶进力的计算进行了理论分析,与实际顶进力进行了对比,最后运用Matlab软件对实测数据进行数值分析,得出在该地质条件下的泥水平衡顶管摩阻力和顶进力计算公式。
Take the example of reconstruction project of Yitong River drainage pipelines in Changchun, based on the change of jacking force measured in jacking process by using slurry balance pipe jacking in medium coarse sand formation, the factors affecting jacking force and the changing rule were systematically studied, and the calculation of jacking force were analyzed and compared to the field measured data, finally the measured data were numerically analyzed with Matlab software, calculation formulas of jacking force and friction under the condition of medium coarse sand formation were deduced.
