A year's journey of plaid poetry

Let me answer this question. As a leading country in high-speed rail technology in the world, China has built a number of ring-shaped high-speed rails. So why build a circular high-speed rail? What are the advantages and disadvantages of circular high-speed rail? What's the difference between ring high-speed rail and other types of high-speed rail? I mainly answer this question around these questions and share my understanding of G5555 high-speed rail.

At the end of 2065438+2009, Lunan high-speed railway was completed and opened to traffic. At the same time, in the timetable of Lunan high-speed railway, three trains stop at the same station, namely G5555/8 and G5557/6 from Jinan to Jinan, and G5565/8 and G5567/6 from Jinan west to Jinan west. These three pairs of trains are the first high-speed railway around Shandong, that is, the ring high-speed railway. From this route map, we can see that the circular high-speed railway in Shandong connects with some sections of Beijing-Shanghai high-speed railway, Qing Ji high-speed railway and Lunan high-speed railway, forming a circular circle of major cities in Shandong Province.

This ring-shaped high-speed rail ring runs through the major cities in Shandong and connects all the cities. This is the first circular railway in Shandong. Strictly speaking, this circular railway is a combination of all railway resources.

So why build a circular high-speed rail? What are the advantages and disadvantages of circular high-speed rail? Regarding the high-speed rail planning, I believe many people know the eight vertical and eight horizontal planning. Our country's overall road network planning is eight vertical and eight horizontal, that is, covering all parts of the country with a grid road network spanning north, south, east and west. Many factors in the planning and design of high-speed railway are based on the optimal decisions of population, geography and economy. The grand plan of our country is to play a game of chess all over the country, which is in line with various factors of our country.

However, planning at the local level below the national level is different. The planning of regional high-speed rail also needs to consider many factors, such as the high-speed rail around Hainan Island, which is determined by many factors such as the topography of Hainan Island. In fact, in a certain area, especially in densely populated areas of small cities, building some circular buildings on the basis of vertical and horizontal buildings is more conducive to mutual communication. For example, in the early stage of subway construction in big cities, it is always built vertically and horizontally. Later, after the urban population reaches certain requirements, one or even several loops will be built.

Therefore, the construction of circular high-speed rail in Shandong is determined by many factors such as the geographical city of Shandong. As for the benefits of circular high-speed rail, it goes without saying that all cities are connected in series on a line to facilitate linkage; The disadvantage is that if there are no vertical and horizontal direct lines, some places on the ring road will take a long journey.

What's the difference between ring high-speed rail and other types of high-speed rail? I will define other types of high-speed rail as non-circular high-speed rail for the time being. Let's talk about the essence of high-speed rail. In fact, the essence of high-speed rail is a means of transportation, which may be to transport goods or people. From one city to another, it helps goods or people to move in space, and the starting point and the ending point may have a circular high-speed railway station. Although someone got off the bus halfway, this kind of high-speed rail basically didn't realize everyone's spatial movement, so it came around a corner.

Turn around, which reminds us of traveling. Some scenic spots have set up some circular passages. Turn around to see the scenery, return to the entrance, and you can leave. Therefore, the circular high-speed rail has the function of sightseeing while helping others to transfer space. For example, if I want to see a city in Shandong, I can start from Jinan and turn around and return to Jinan without getting off! This brings great convenience to sightseeing.

The future of circular high-speed rail With the increasing density of railway network, it is the general trend to operate circular lines in small areas. I believe that in the future, more and more urban agglomerations or regions will have their own circular railways, which are very suitable for sightseeing or convenient travel.

This is my opinion, not enough.
