由同济大学侯学渊教授等承担的“注浆法在控制顶管上方铁路沉降中应用研究”课题于1988年10月27日通过专家评审鉴定。专家们一致认为,在软土地基中采用注浆法来防止地层沉降是一项新技术,其方案合理,效果显著,可成功地控制地层的沉降。经济、社会效益显著,该技术应用前景广阔,成果属国内首创。在市政工程设计中,常用顶管法、盾构法来进行地下隧道和管道的施工。施工时,保证不危及地层中的已有管线和地面建筑是一个十分重要的问题。
By the Tongji University, Professor Hou Xueyuan bear the “Grouting method in the control of pipe jacking above the railway in the application of research” issue on October 27, 1988 through expert assessment identified. Experts agreed that the use of grouting method to prevent formation subsidence in soft ground is a new technology with reasonable scheme and remarkable effect, which can successfully control the settlement of strata. Economic and social benefits are obvious. The application of the technology has broad prospects and the achievements are the first in China. In municipal engineering design, commonly used pipe jacking method, shield method for underground tunnels and pipe construction. During construction, it is a very important issue to ensure not to endanger the existing pipelines and ground structures in the formation.
