桥头跳车,一直是公路建设中很难攻克的一个顽症,尤其是在沿海、湖泊等平原水网地带,软土厚度大、埋藏深,深达几十m至上百m不等,含水量大、透水性差、强度低、存在沉降量较大且历时较长,易产生不均匀沉降等问题,影响道路建成后的使用功能。本文结合浙江省瑞安市东新公路建设的实际情况,谈谈水泥搅拌桩的应用情况及水泥搅拌桩设计原理与方法。
The bridgehead jumping has always been a chronic problem difficult to overcome in highway construction. Especially in coastal waterways, lakes and other plain water networks, the thickness of soft soil is large, deep buried and deep, reaching tens of m to over a hundred meters. The water content is large , Poor water permeability, low strength, large settlement and lasted for a long time, easy to produce uneven settlement and other issues, affecting the use of the road after the completion of the function. In this paper, the actual situation of East New Road in Ruian City, Zhejiang Province, to talk about the application of cement mixing piles and cement mixing pile design principles and methods.
