An updated version of the technical guide for the construction of railway tunnels has been published in accordance with the Government ' s railway development plan and guidelines。 The guide details the preparation of the tunnel works， the
construction methodology， security measures， etc。 Detailed surveys and designs must be carried out to determine parameters such as the location， length and depth of the tunnel prior to its construction。 Subsequently， preparations were made for the construction of the tunnel， including the preparation of road bases and holes， the preparation of construction equipment and materials。 During the tunnel construction process， the construction methods are essential， and the usual construction methods include drilling， blast and shield construction。 Security measures at construction sites， including ventilation， fire protection and drainage， are also essential。 These regulatory construction techniques and security measures will contribute to the efficient， safe and sustainable development of railway tunnels， in line with the overall development of national railways。
根据制定的铁路发展规划和方针，铁路隧道工程施工技术指南最
新版已经发布。该指南详细包括了隧道施工的准备工作、施工方法、安全措施等内容。在进行隧道施工前，必须进行详细的勘察和设计，以确定隧道的位置、长度、深度等参数。随后，要进行隧道施工的准备工作，包括路基和洞口的准备、施工设备和材料的准备等。在隧道施工过程中，施工方法至关重要，常用的施工方法包括钻孔法、爆破法、盾构法等。施工现场的安全措施也是不可或缺的，包括通风、防火、排水等各项安全措施。这些规范的施工技术和安全措施将有利于促进铁路隧道工程的高效、安全、持续发展，符合国家铁路建设发展大局。
A lot of preparatory work has to be done before the tunnel works。 First we have to look at the geology， see what the foundation is， and we have to design the location， length， depth， etc。 The construction site will then bepleted， the foundations and holes will be organized and construction equipment and materials prepared。 These preparations have to be well prepared and can be important for tunnel construction。
在搞隧道施工之前，得先搞好一堆准备工作。首先得查查地质，看看地基啥情况，还得设计隧道的位置、长短、深浅啥的。然后得把施工现场弄好，整理好路基和洞口，准备好施工设备和材料。这些准备工作得做得充分细致，对隧道施工可是很重要的。
Tunnel construction methods are a keyponent of tunnel
construction。 As construction technology continues to develop， tunnel construction methods currentlymonly used include drilling， blast and shield construction。 The drilling method refers to the drilling of holes using a drill machine， followed by the detonation of tunnels by various means。 The blast method uses explosive materials， such as explosives， to explode in tunnels， to loosen rocks and then to clean them up。 The law on shield construction refers to the use of shields for tunnel excavations， which can be apanied by soil support and tunnel excavations with less environmental impact on the surface。 Depending on the circumstances。 Safety measures at the construction site， including ventilation， fire protection and drainage， are also essential to ensure the safety of construction personnel and equipment。
隧道施工方法乃隧道施工之关键环节。随着施工技术之不断发展，目前常用之隧道施工方法包括钻孔法、爆破法以及盾构法等。钻孔法係指利用钻孔机进行钻孔，随后通过各种方式进行爆破，以便挖掘隧道。爆破法则利用炸药等爆破材料，在隧道内进行爆破，使岩石松动，再进行清理。盾构法则是指利用盾构机进行隧道开挖，可同时进行土壤支护及隧道挖掘，对地表环境影响较小。此等施工方法各有其优劣，
当视具体情况而定。施工现场之安全措施亦为极为重要，包括通风、防火、排水等安全措施，以确保施工人员及设备之安全。
