我国深基坑支护技术的进展

Progress in the Support Technology of Deep Excavation in Our Country

近20年来,我国各大中城市高层建筑拔地而起,上海金茂大厦等众多高层跻身于当今世界20座超级巨厦之列,令人瞩目。同时,这些已建和在建的高楼,其基坑深度已逐渐由6m、8m发展至10m、20m以上。伴随着这些工程的大实施,深基坑支护工程的设计、施工技术已取得了长足进步,文章就此进行分析总结。

Numerous high-rise buildings have sprung up in the large or medium-sized cities in our country over the past 20 years, among which the remarkable high-rises such as Shanghai Jinmao Mansion have been listed among the top 20 highest buildings in the world. The the depth of the deep excavation for these building or built high-rises has subsequently grown from 6m to 20m or even more. The article makes analysis and conclusion of the progress made in the support engineering of the deep excavation.
