人工地层冻结技术在我国城市地下工程中的兴起

以作者亲历的开创性的典型工程,展示了人工地层冻结近10年的发展历程。杨树浦水厂基坑冻结围护工程的独特大胆引用、北京地铁隧道水平冻结的技术攻关,上海、广州地铁隧道水平冻结技术的深化和完善,历史的机遇和从事地下工程建设的科技人员的不懈努力和艰苦奋斗,使得我国人工地层冻结技术跨越到一个新台阶。地层冷冻技术就像技术海洋中的一滴,映射出我国改革开放年代科学技术的蓬勃发展的光辉。

AGF Technology Rises in the Urban Underground Engineering of China

With several typical projects directed by author, this paper introduces the development history of AGF technology in recent 10 years. It is audacious and careful practice to use AGF to brace a pit without previous experience in Yashupu pumping building underground engineering in Shanghai. It is innova-tional to complete the first horizontal ground freezing tunneling engineering with several key technique breaks through by self-dependence, furthermore, it is promotional and profound to spread this successful technique in Shanghai and Guangzhou underground engineering. Much like a drops to the o-ceans, such a development course raising AGF technique to new level maps out our science and technology achievements in the open times.
