中文拼音 [chāobiǎnpíng]
超扁平
英文
superflat-
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。Flat contact surfaces for earthing screws ; rated voltage not exceeds 52 kv
接地連接螺栓的扁平接觸表面.額定電壓不超過52kvHis glance was keen but showed cunning rather than intelligence ; his lips were straight, and so thin that, as they closed, they were drawn in over the teeth ; his cheek - bones were broad and projecting, a never - failing proof of audacity and craftiness ; while the flatness of his forehead, and the enlargement of the back of his skull, which rose much higher than his large and coarsely shaped ears, combined to form a physiognomy anything but prepossessing, save in the eyes of such as considered that the owner of so splendid an equipage must needs be all that was admirable and enviable, more especially when they gazed on the enormous diamond that glittered in his shirt, and the red ribbon that depended from his button - hole

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。Non - destructive testing - ultrasonic testing of austenitic and austentitic - ferritic stainless steels flat products of thickness equal to or greater than 6 mm reflection method
