摘要
HDPE(high-density polyethylene,即高密聚乙烯)螺旋管以其独特的优点,在工程中有着十分广泛应用前景。主要针对上海软土地基的特点,根据现场施工条件来模拟试验加载方案,对大型HDPE螺旋管在不同的加载阶段的管道的受力与变形规律以及管–土共同工作机理进行了分析,以便为大型HDPE螺旋管在工程中应用推广提供可靠理论依据。通过对试验测试数据的整理分析,给出了在上海软土地区大型HDPE螺旋管的埋设方式、合理管沟尺寸、覆土层厚度以及密度等有关参数,并为其工程应用提出相关技术要求和建议,供相关工程设计和施工人员参考。
HPDE (high-density polyethylene) spiral pipe has a broad application prospect for its unique properties. In a test on its application in soft soil area of Shanghai, the loading scheme simulates the load situation of practical projects. The mechanics-deformation patterns of HPDE spiral pipe and pipe-soil interaction mechanisms in various experimental stages are analyzed based on the test data and properties of soft soil in Shanghai, which offers the theoretical basis for its application in engineering field. Some suggestions and technical requirements are provided for design and construction in Shanghai in aspects such as laying style, rational channel dimension, and thickness and density of backfill.
