1. According to Deputy Director Zou, the cracking of the railing is mainly caused by the cracking of the root of some railing columns of the northwest approach bridge abutment and the tenoning of the railing.
2. First, the root of some railing columns is cracked, and second, the railing of the northwest approach bridge abutment is tenoned.
3.SME is widely used in abutment with high compressibility soil.
4. Strengthening the existing abutment is the key to control the construction period and ensure the normal operation of the line.
5. At the same time, it is found that the railing of the abutment of the northwest approach bridge has tenons.
6. Zou Jianping said that the cracking of the railing was mainly caused by the cracking of the root of some railing columns at the abutment of the Northwest Approach and the tenoning of the railing.
7. This stone bridge consists of stone piers, abutments and arches, which are bonded together with mortar.
8. The upper part of the bridge is arched with stone, the lower part is built with stone abutment, and the bottom of the bridge is built with stone to support the foot of the bridge.
9. This paper mainly studies the mechanical characteristics of skew rigid frame bridge with inclined legs without abutment.
10. By analyzing the main problems existing in the skew bridge, a new type of bridge-slant-legged rigid frame bridge without abutment is proposed to solve the problems existing in the actual operation of the skew bridge.
1 1, multi-hole slant-legged rigid frame bridge without abutment is a high-order statically indeterminate structure with great potential for structural optimization.
12. Through research and analysis, some suggestions are put forward for the engineering design of integral abutment bridge.
13, Zou Jianping, deputy director of the Nanjing Municipal Construction Committee, announced that the bridge did have two problems, one was that the root of some railing columns was cracked, and the other was that the railing at the abutment of the Northwest Approach Bridge was tenoned.
14, the stone arch bridge of Jianning-Fengfeng highway has been used for many years, and abutment subsidence and local structural cracks appear. Grouting is used to strengthen the foundation, and the upper arch and lower inverted arch are combined to strengthen the foundation, which has achieved good engineering results.
15. Another problem is that the railings of the northwest approach bridge abutment have tenons.
16. The inclined leg rigid frame bridge without abutment is similar to a broken-line arch bridge, and the soil on the inclined struts at both ends of the bridge actually forms a pair of arch thrust.
