地下工程注浆理论研究现状

Grouting Technology for Underground Works

随着地下隧道工程及井巷工程技术的迅猛发展,越来越多的工程实践证明:在工程地质和水文地质较复杂的地下工程中,注浆技术已成为保证工程质量和安全的经济而有效的新型技术。由于地层内部构造复杂多变,浆液在地层中流动的隐蔽性以及浆液自身性质的多样性,给地下工程注浆理论的研究带来了很大的困难。文章对现有地下工程注浆理论做了比较深入的探讨。

With the rapid development of technology on tunnel engineering and mine excavations, more and more project have proved that grouting is a new economical technology and can ensure security and quality in underground works with complex engineering geology and hydroge- ology. Complexity and variability of internal structure of strata, invisibility of grouting flow in strata and qualitative diversity of grouting hquid make the study of grouting theory very difficult. The existing grouting theory is discussed in depth in this paper.
