深基坑土方岛式开挖施工技术

On construction technology of earthwork island excavation of deep foundation pit

结合具体工程实例,重点介绍了深基坑土方岛式开挖技术,提出了土方开挖的原则,阐述了在现场狭小环境下的土方工程施工步骤,以积累深基坑土方开挖经验,保证深基坑工程的顺利进行。

By combining with factual examples,the paper points out the principle of the earthwork excavation,mainly introduces the earthwork island excavation of deep foundation,and indicates the earthwork construction s steps in narrow fields,so as to accumulate the earthwork excavation experience of the deep foundation and to ensure the smoothness of the deep foundation construction.
