tunnel flat 中文意思是什麼
tunnel flat
解釋
軸道甲板-
Due to exceedingly flat arched vault of the flat tunnel with outsized span and renewed stress allocation in surrounding rock after excavation, which would inevitably induce some excessively large load on the base of arch, therefore, larger load - bearing capability in the is " foundation is a must. on the other hand, smooth face explosion must be applied to excavation of the arch base to further ensure the integrity and continuity of country rock around tunnel
特大跨超淺埋隧道拱部結構過于扁平，開挖后發生二次應力分佈，拱腳處的應力過大，要求有較大的地基承載力，拱腳開挖時必須採用光面爆破，保證圍巖的完整性和不受擾動，開挖后及時封閉，防止該處積水軟化圍巖。 -
Wind tunnel investigation of large span flat roof was carried out. mean local shape factor and extreme local shape factor distributed on the roof of the structure with two exposures are measured. effects of terrain exposures on the mean local shape factor and extreme local shape factor are discussed
然而，對于大多數的屋蓋結構，由於其自身結構和風荷載的復雜性，我國的有關荷載規范中並沒有這方面的建議條文，因此對于大跨度屋蓋結構風荷載特性的研究，已成為一項急需進行的重要課題。 -
Special emphasis is laid upon the construction operation process of flat tunnels with outsized span at even shallow depth, meanwhile, how to build large span flat tunnel is briefed in this article. measures taken to reduce vibrations caused by explosion in driving tunnel and surface subsidence and methods of monitoring and surveying in the course of construction are detailed in this article
本文扼要介紹了大跨扁平隧道的施工方法，重點闡述了特大跨超淺埋扁平隧道的施工工藝過程，對爆破振動和地表沉降的控制方法，以及施工監控量測的過程和方法，並通過對量測結果的分析，說明監控量測對施工的指導作用，並對圍巖穩定性進行了一些簡要分析。 -

Construction of flat tunnel of large span at extra - shallow depth must be conducted on the principle that advance grouting should be strictly performed before excavation and length of pull at one time should be short, together with reinforced support, immediate closing and constant monitoring and surveying. that preceding pilot tunnels, large - volume excavation divided into small ones, excavation of flank before that of center, upper before lower, arch before wall etc is a good method which could effectively reduce surface subsidence and its adverse effect on adjacent buildings, in addition, some other measures are also taken to lessen blast - induced vibration in the ground and surrounding structures. in a word, all means and steps mentioned above have already proved effective and practicable in practice
軟弱大跨超淺埋扁平隧道必須按「管超前，嚴注漿，多分部、短開挖、強支護、快封閉，勤量測」的施工原則進行施工，採用「眼鏡超前，化大為小，先側后中，先上後下，先拱后墻」的施工方法控制地表沉降和對周邊建築物的影響；採用「多分部，化大為小，短進尺，密布眼，弱裝藥，設減振槽」 ，控制爆破振動，經過實踐證明，這些方法都是行之有效的。 -
Special attention should be paid to the flat tunnel with outsized span at shallow depth. apart from some common surveys, it is quite necessary to survey initial support stress, which is conducive to directly and accurately understanding changes of stress in surrounding rock and can provide helpful guidelines for governing tunnel construction in an importantly practical way
施工中必須進行監控量測，淺埋特大跨隧道施工除需進行常規項目量測外，必須進行初期支護應力量測，這樣可準確、直觀了解圍巖應力變化情況，對指導隧道施工、預防險情有著非常重要的現實意義。 -
