【摘要】 针对预应力钢筒混凝土管(PCCP)在软土地基中可能遇到的管道上浮、地基承载力不足、管线沉降、地震作用等问题进行分析,提出解决以上问题的方法。通过本文的分析可知,预应力钢筒混凝土管(PCCP)在软土地基上具有良好的适应性,且柔性接口是其良好地基适应性的关键。更多还原

【Abstract】 In this paper,the floation、subsidence、response of seismic action of PCCP pipeline on the soft subgrade and the bearing force of soft subgrade are discussed.The method to sllve the problems above was also pointed out.PCCP pipeline has better suitability for soft subgrade,the key is its flexible joints.更多还原
