沪宁高速公路拼宽复合地基处理效果分析
nalysis of Improvement Effect with Analysis of Improvement Effect with Composite Foundation Method for Widening Engineering of Shanghai to Nanjing Expressway
本文根据沪宁高速公路拓宽工程实践，分析了拓宽路基的总体沉降变形规律，讨论了不同路段位置及不同方法处理的拓宽路基沉降，总结了拓宽工程中采取的水泥搅拌桩、PTC管桩、浅层换填以及由于施工条件被迫选取的素混凝土桩和高压旋喷桩处理方法的实际表现。
Based on the widening practice of Shanghai to Nanjing expressway，the rule of settlement of the embankments widening is explored; the influence for settlement of position and treatment measures are discussed; the actual performance of mixing piles, PTC piles, shallow replacement , pure concrete piles and high-pressure rotary jet piles are investigated.
