摘要

由于城市越來越擁擠，高速公路、地鐵等交通建設(shè)日益頻繁。在建設(shè)過程中，長距離超近鄰隧道是一種新型隧道形式，以其優(yōu)異的經(jīng)濟(jì)效益和較高的安全性備受關(guān)注。但是，在其建設(shè)的過程中，難免會受到盾構(gòu)施工的影響。為了解決這些問題，本文選擇典型的隧道段，對盾構(gòu)施工的影響進(jìn)行深入分析，并對其對長距離超近鄰隧道施工及使用的影響進(jìn)行研究。

涉及到盾構(gòu)推進(jìn)施工對長距離超近鄰隧道的影響，我們首先考慮建筑材料的選擇。本文提出了一種全新的隧道充填材料的組合，并將其與常規(guī)材料進(jìn)行了對比，結(jié)果顯示其在隧道施工中有著非常高的性價比。此外，本文也分析了隧道軌道在盾構(gòu)施工中的變形情況。經(jīng)過分析，本文認(rèn)為采用新型材料和加強(qiáng)對隧道軌道的監(jiān)控可以更加有效地保證隧道的安全和穩(wěn)定。

此外，本文還研究了盾構(gòu)推進(jìn)施工對長距離超近鄰隧道的噪聲、振動方面的影響。為了解決這些問題，本文提出了一種新型隔聲吸聲隔板的設(shè)計，并對其進(jìn)行了仿真實驗，證明其在降低噪聲振動方面有著非常有效的效果。
