Big bridge suit smoothly approach end establish and transport test as well as safe operation for two year , all of these have proved the reasonability of the inspection and its data analysis handling and correctness of construction control 并通过大桥的顺利合龙和建成及其通车试验和近二年的安全运营证明了施工控制的正确性、监测及其对其数据分析处理的合理性。
The bridge design theory based on the life cycle cost refers to , in the beginning of bridge design , the innovative design approach to ensure an optimized bridge life cycle cost on the basis of a secure operation of bridge 所谓桥梁的全寿命周期成本设计理论,即指在桥梁结构设计之初,在保证桥梁服务寿命内安全运营的前提下,确保其寿命周期成本最优化的一种全新设计方法。
During the next month , a subcommittee of the corporate safety steering committee will reanalyze data from the past four years of incidents at company x facilities to cull the human factors that played a role in those accidents 接下来的一个月，公司安全运营委员会小组委员会针对x公司各种设施在以往四年内所发生的事故数据进行再次分析，挑出在这些事故中起重要作用的人的因素。
The absorption equipment system for ammonia leakage may be used to handle ammonia leakage accident rapidly with high efficiency , providing a reliable safety shield to the water plant in ammonia use , thus ensuring the sound operation of the water plant 氨气泄漏吸收设备系统可以高效、快速地应对和处理氨气泄漏事故，致力于为自来水厂氨气使用过程提供可靠的安全屏障，确保自来水厂安全运营。
The purpose of this paper is to research the development strategy i . e . cost prevailing strategy for ipp , discover some effective measures for ipp to realize the strategy and study quantitatively on the safety operation strategy with least cost 本文主要研究独立发电公司的企业发展战略- - -成本领先战略；探讨独立发电公司实施成本领先战略的有效措施；并对独立发电公司最低成本安全运营战略进行定量化研究。
But the railways in the west of china , which were always built in the so called " railway forbidden region " , are often attacked by debris flow , landslide , mountain torrents and so on , the railways are threaten by these nature disasters deeply 而在我国西部广大的山区，婉蜒伸展的铁路往往是建在被认为是“铁路禁区”地带，经常受到滑坡、崩塌、泥石流、山洪等自然灾害的侵袭，铁路的连续安全运营受到严重威胁。
The transportation security administration ( tsa ) headquarters buildings and the transportation security operations center ( tsoc ) have been designated as level iv federal facilities pursuant to the guidelines established in the 1995 department of justice directive entitled , “ vulnerabilities of federal facilities 依照1995年司法部定立的“联邦设施易受攻击程度”准则，交通安全管理总部大厦和交通安全运营中心被列为四级联邦设施。
Dynamic and static tests are needed in order that the construction characteristics and forced conditions must qualify for the requirement of designing standard and safe run , at the same time , the test can give a reference of the bridge designing 检验桥梁结构特性及其工作状态是否符合设计标准和使用要求，以保证桥梁今后的安全运营，需要对已建成桥梁进行动静载荷载试验。通过动静载荷载试验为桥梁结构设计提供参考依据，是桥梁建设中必不可少的一个重要环节。
Stay cables of the long - span cable - stayed bridges are susceptible to vibration under wind loading , or wind incorporated rain excitation , or deck motion due to high flexibility , relatively small mass and very low inherent damping , such as vortex shedding , wake galloping , parameter resonance and wind - rain induced vibration . large - amplitude vibration of cables may reduce the life of cables and threaten safe traffic , and has been considered today as one of the most critical problems for this type of bridge 大跨度斜拉桥拉索具有较小的质量和极低的阻尼，在风、风雨及桥面振动等外部激励下极易发生振动，如涡激共振、尾流驰振、参数共振和风雨振等，拉索的大幅振动对拉索的使用寿命和桥梁安全运营构成极大威胁，它已成为大跨度斜拉桥急需解决的关键问题之一。
The standard in bridges " designing load in xuanhua - datong speedway is auto - super 20 , trailer - 120 . because of transiting carrying coal vehicle mostly , investigating and measuring all vehicles carrying coal in 109 and analyzing and checking strength and intension of new bridges . in this way , ensuring to advance loading measure of over load and assuring safely operation in bridges according to the standard in bridges " designing load 宣大高速公路桥梁设计荷载标准为汽车?超20级，挂? 120 ，公路建成后主要通行运煤重载车辆，为此对现有高速公路旁全部的109国道运煤车辆进行调研、量测，并以此对新桥梁结构受力及强度进行了分析及验算，以确定对重载车辆提出发载措施，保证按高速公路桥梁设计荷载标准设计的桥梁能够安全运营。
