摘要： 随着经济的快速发展，城市人口的迅速增加，城市建设也接踵而来。城市建设用地也愈来愈紧张，施工过程中周边环境的复杂多变，不同施工工序的合理交叉进行，不同施工工艺在不同环境中采用的利弊，如何在有限工期内保质保量的完成工作内容，如何加强施工过程中技术控制。通过多年的现场经验，分析桩基础和基坑支护施工过程中的重难点，并优化一系列的施工工艺，提出施工中常见的问题的解决方案，不但为该类施工过程控制提供一定的技术支持，减少工程事故的发生，达到节约资源、降低成本的效果。

Abstract: With the rapid development of the economy and the fast increase of the urban population, the issues in the urban constructions are consequently and frequently encountered. The urban construction sites are becoming more and more confined, the surrounding environments are also complicated and variable during the construction periods. The interfaces of different construction sequences and procedures are discussed in the paper. The challenge goal of complete the entire construction work within the tight schedule without compromise the quality by controlling the smooth flow of different construction procedures are evaluated. The key issues and critical points in the deep excavation supporting system and piled foundation construction are analyzed in the paper. The methods of optimizing the construction and measures for resolving the frequently encountered problems are also provided in the paper.


Key words: pile foundations, deep excavation supporting system, cross constructions, construction technology, key issues in the construction
