Length-width ratio requirements of rectangular piers

The length-width ratio of rectangular pier is1.618: 0.618. The strength of high-speed rail bridge piers reaches the bridge label C50, and the piers are generally C30 and C35. There are two main types of rectangular hollow piers used to draw up the foundation dimensions of high-speed railway piers. One is simply supported box girder concrete rectangular hollow abutment, and its length is fixed. The other is reinforced concrete hollow abutment with simply supported T-beam, and its length varies with the height of filled soil. Under the same conditions, the strength of rock-filled concrete blocks cured can reach 65,438+000% before the bridge can be built, which generally takes 28 days and the average temperature is higher than 20 degrees.
