文章以实际工程为例,考虑天津地区软土特性及工程特点对现浇混凝土薄壁管桩施工工法相关问题进行研究。结合现场试验,研究了混凝土坍落度、拔管速度对管桩施工质量的影响,得出了相关结论并对管桩进行了小应变动力测试,研究了小应变检测在现浇混凝土薄壁管桩中的应用。 Taking practical engineering as an example, this paper studies the related problems of cast-in-place concrete thin-wall pipe pile construction method considering the characteristics of soft soil and engineering features in Tianjin. Combined with field test, the influence of concrete slump and extubation speed on the construction quality of pipe piles was studied. The relevant conclusions were drawn and the small-strain dynamic test was carried out on the pipe piles. The effects of small strain testing on cast-in-situ concrete thin- Application of pile.
