随着我国人口不断增加，人们出行压力不断增大。
With the great increasing in population of china, the pressure of transport during people’s trips has been going up.
铁路，作为人们主要的出行方式，面对各大节假日、暑运和春运等出行高峰，铁路部门承受着巨大的运输压力。
Railway, as a main transportation mode for people, faces the peak time on vocations, summer vocation and spring festival and so on. So railway departments have shoulder a great deal pressure of transport.
近年来，我国为缓解运输压力，大力发展高速铁路，随着京津城际高铁、广深城际高铁及武广高铁等相继开通。
In recently years, to relieve the tension of transport, we have devoted major efforts to develop high-speed railway with serving of Jing-Jin Railway, Guan-Sum Railway and Wu-Guan Railway on by on.
面对我国高铁建设“四纵”“四横”客运专线的中长期发展规划，我国将进入高铁的飞速发展时期。
We will come to a fast development of high-speed railway with a medium and long term plan of establishing four-vertical and four horizontal transportation lines
在我国大力发展高速铁路的环境之下，随着设备的不断创新和自动化，列车运行速度不断增加，高铁运输安全是眼下急需提高和完善的重要方面。
With the environment that we are highly developing high-speed railway, while the facilities have been being upgraded, the speed of railway keeps increasing. So the safety of high-speed railway is an important part that should be reinforced and completed.
由于高铁发展盲目追求速度而忽略运输安全，近期，7.23动车事故的发生以及新开高铁线路事故频发，高速铁路发展遇到了瓶颈，所以更体现出高速铁路运输安全研究是多么急需了。
Because the development of railway mainly aim at speed without enough programs and ignore the safety of transport, recently, a vital train accident happened on 23rd, July and other accidents happened in some new high-speed railways in so frequent times. Now the development of high-speed railway has come to stuck, which inferes the importance to study the safety of it.
为了更好做好对高度铁路运输安全方面的研究，为此本文专门对我国高速铁路运输设备安全、管理等方面来研究，结合近期发生的7.23动车事故、京沪高铁事故等等来对高铁运输安全进行分析。
To prepare better for the studying in safety of high-speed railway, this paper aim at studying the safety of facilities and management of high-speed railway transport, and make an analysis combining with the train accident on 23rd, July and Jing-Hu high-speed railway accident and so on.
语法没问题，就是一两个专业词汇不怎么确定，比如说‘四纵四横’，查不到专业的表达，所以我就自己想了个。。。= =！有问题楼主指正下 欢迎继续追问
