公路软基预制管桩处理间距优化现场试验数据分析

摘要

This paper selects 3 tubular pile construction sections along some expressway and sets 8 observed sections at 5 different values of pile spacing and conducts comparative test to study key techniques in optimization of spacing between tubular piles.%在某高速公路沿线选取3个管桩施工路段,设置5种不同桩间距的8个观测断面并进行对比试验,研究管桩间距优化关键技术.
