The five rail systems include a heavily - used mass transit system , a busy suburban railway , a modern light railway , a traditional street tramway and the peak funicular railway 本港共有5個鐵路系統(tǒng),計有使用率很高的地下鐵路集體運輸系統(tǒng)、繁忙的郊區(qū)鐵路、現(xiàn)代化的輕便鐵路、傳統(tǒng)的電車,以及山頂纜車。
This paper is based on the construction of jiangbei airport station of the chongqing no . 3 light railway , the control demolition applied to shallow covered and large foundation pit excavation under urban complicated condition is introduced 摘要以重慶輕軌三號線江北機場站為例,介紹了城市復雜環(huán)境條件下淺埋隧道、大基坑開挖控制爆破施工方法。
3 . the ground vibration caused by load of vehicle in light railway system is analyzed as well . different from the common railway and subway , the viaduct is the main structural member in light railway system , which is studied in specialty in this paper 3 、關于輕軌列車荷載作用下的地基土的振動分析,本文考慮到輕軌的結構形式一般為高架橋,與普通鐵路和地鐵不同,因此,本文對這一問題進行了專門研究。
Combined with the real example of monitoring pressure on the supporting system in the long span underground space of dk7 + 692 section at jiao - xin line of chongqing light railway , it is set forth the methods about choosing the support system and its parameter , digging methods of underground space , measuring and testing methods for the stress of the support system ; the testing results and variation pattern were analyzed for the stress of the initial supporting i - steel axial stress of bolt , stress of shot - concrete , supporting pressure of temporary i - steel and stress of steel of the second lining , then , the reason for deformation of the support system induced by sharp increase of i - steel was determined 摘要結合重慶市輕軌較新線大坪車站大跨度地下空間dk7 + 692斷面施工支護體應力監(jiān)測的工程實例,闡述了該大跨度地下空間支護結構的參數(shù)選擇、地下空間的開挖方法、支護體結構的應力量測方法及測試手段;分析了支護體初期支護工字鋼拱應力、錨桿軸力、噴射混凝土內應力、臨時工字鋼支撐應力、二次襯砌鋼筋應力等測試結果和變化規(guī)律;確定了工字鋼拱應力急劇增大而可能引起支護體系失穩(wěn)的原因。
Transit and rail industries in many nations have already adopted the digital system as their regular radio communications system . in asia for example , the digital trunked radio system has already been adopted for system expansion or replacement by several organizations . these include the transit northeast line in singapore 1991 , the mass transit system smrt in singapore 1998 , the high speed railway in malaysia 2000 , the guang - zhou subway in china 2000 , the west line of guang - jiu railway in china 2000 , the peking light railway in china 2001 , and the new delhi transit system in india 2001 據(jù)了解現(xiàn)在各國新建捷運路網無線電系統(tǒng)規(guī)劃方式,有往數(shù)位干線式無線電系統(tǒng)發(fā)展之趨勢,并且已成各國捷運及鐵道工業(yè)無線電通信的主流標準,以亞洲為例:新加坡捷運東北線( 1998年) 、新加坡高運量捷運smrt ( 1998年) 、馬來西亞快速鐵路( 2000年) 、中國廣州地鐵( 2000年) 、中國廣九鐵路西線( 2000年) 、印度德里捷運( 2001年) 、中國北京輕軌系統(tǒng)( 2001年) .均已于系統(tǒng)擴建或新建時規(guī)劃采用數(shù)位干線式無線電系統(tǒng)。
The means of transportation that i chose at ordinary times is the rail transportation basically , the subway or the light railway , because and fast , so long as than estimate more about one minute such as time , would not be late , and though its crowded degree is a bit serious , as to traffic above - ground , ones that can be accepted , will not seem too hot or too cold in hot summer and cold winter 我平時選擇的交通工具基本上是軌道交通,地鐵或輕軌,因為相對而言比較準時而且快速,只要比預計時間多出15分鐘左右,就不會遲到了,而且其擁擠程度雖然有些嚴重,但相對地面交通來說,還是可以接受的,在炎熱的夏季和寒冷的冬季,都不會顯得太熱或太冷。
In second part , the feasibility and necessity that a internuncial line of the railroad hinge ( lishu bay - cai yuan dam ) participate in new no . 1 light railway in chongqing is analyzed , at the point of technology and economy , at the same time , the pattern of operation and management is being probed . at last , the methods of joining and transferring among state railway . outskirts railway and routine public traffic is been analyzed 本文第二部分對重慶鐵路樞紐內梨樹灣至菜園壩一條重要聯(lián)絡線參與重慶輕軌交通新號線進行研究,首先介紹重慶市客運現(xiàn)狀和交通路網現(xiàn)狀,結合重慶市鐵路樞紐的調整規(guī)劃,通過對梨菜線參與城市軌道交通的幾種運營模式和管理模式的比較,提出了一個比較適合重慶市特點的運營管理方案,并從技術、經濟、政策方面分析了其可能性和可行性。
So ansys is applied here to calculate the response of ground under moving loads in light railway system . at the locations with the big vibration , two measures for vibration - diminishing ? wave impeding block and open drain for isolating vibration are constructed , and the effective of vibration - diminishing is analyzed 因此在計算輕軌列車荷載作用下地基土的響應時,本文運用ansys軟件進行模擬,在振動較大的地方采用設置阻波區(qū)( wib , waveimpedingblock )和隔振溝兩種減振措施,同時對減振效果進行分析比較,得到了較為理想的結果。
