据报道,中国矿业大学留美回国的翁家杰教授在液氮冻结温度场和液氮冻土特性等研究中,在世界上首次以数理关系形式揭示了液氮冻土发展规律和冻土冻结强度与冻结温度之间的应变关系,使我国在这一领域迈入世界先进行列。1992年中国矿业大学与中煤特殊凿井公司和上海隧道工程公司合作,首次在上海地铁工程中应用液氮冻结技术获得成功。翁家杰留学期间,利用有限差分和计算机模拟技
According to reports, China University of Mining and returned from the United States, Professor Weng Jiajie in liquid nitrogen freezing temperature field and liquid nitrogen frozen soil properties and other research, the first time in the world to reveal the relationship between the law of liquid nitrogen frozen t frozen soil freezing and freezing strength The relationship between the strain of temperature, so that our country in this area into the world’s advanced ranks. In 1992, China University of Mining cooperated with China Coal Special Sinking Company and Shanghai Tunnel Engineering Corporation for the first time and successfully applied liquid nitrogen freezing technology in Shanghai Metro Project. Weng Jiajie during the study, the use of finite difference and computer simulation technology
