tunnel excavation

基本解釋

For a large span tunnel, this paper from the Monitoring the development and implementation of programs such as a large span of the tunnel excavation method.
針對(duì)大跨度隧道施工，本文主要從監(jiān)控量測(cè)方案的制定和實(shí)施等方面淺談了大跨度隧道開(kāi)挖施工方法。
Therefore, this article analyzes the reasons that generating loess collapse in tunnel excavation and how to prevent collapse in the construction is briefly discussed.
為此，本文分析了在黃土隧道開(kāi)挖中產(chǎn)生坍塌的原因，對(duì)如何在施工中預(yù)防坍塌進(jìn)行了簡(jiǎn)要的探討。

On the puzzle of dynamic simulation of tunnel excavation with centrifuge model, this thesis makes a trial research on the section of SK3+395 of Shenzhen Metro and has made some progress.
并針對(duì)動(dòng)態(tài)模擬隧道開(kāi)挖這一難題利用離心模型對(duì)深圳地鐵SK3+395斷面進(jìn)行了嘗試性的研究，取得了一定的進(jìn)展。

隧道開(kāi)挖
The surrounding rock forms the new discharge passage after tunnel excavation, and intensifies the interactions between water and rock.
隧道開(kāi)挖后形成新的地下水排泄通道,加劇了地下水對(duì)巖體的作用。

隧洞開(kāi)挖
. So it is necessary to study and discuss to tunnel excavation and lining ulteriorly. At first, a elasto-plastic finite element analysis model was applied to simulate the conventional procedure of tunnel excavation and lining with the finite element.
因此,尚有必要對(duì)隧洞開(kāi)挖問(wèn)題作進(jìn)一步的研究和討論。
