大直径现浇的混凝土薄壁筒桩截面抗弯刚度大,每延米消耗混凝土量较低,在基坑工程中作为围护结构的重要组成部分具有良好的工程前景,尤其是在沿海的软土地区。通过温州某深基坑工程中现浇薄壁筒桩的成功应用,分析比较了不同支护形式的技术指标,详细阐述了薄壁筒桩在软土地区基坑工程中的优越性。 The large-diameter cast-in-situ concrete thin-walled tubular pile section has great flexural rigidity and low consumption of concrete per meter, which has good engineering prospect as an important part of the envelope in the foundation pit project, especially in the soft coastal areas Land area. Through the successful application of cast-in-situ thin-wall tubular piles in a deep foundation pit project in Wenzhou, the technical indexes of different supporting forms are analyzed and compared, and the superiority of thin-wall tubular piles in the excavation of soft soil area is expounded in detail.
