Viaduct construction method involving underlying tunnel protection
The invention discloses a viaduct construction method related to underlying tunnel protection, and relates to the technical field of stratum reinforcement and viaduct construction, and the viaduct construction method comprises the following steps: calculating the load transmitted from a viaduct pile foundation to a soil layer reinforcement area, reinforcing a 20-40mm thick steel ring lining in an original reinforced concrete lining of an underlying tunnel, and improving the bearing capacity of the underlying tunnel. Ground grouting reinforcement is conducted on a soil layer above the tunnel, the reinforcement strength of the soil layer meets the requirement for the load transmitted to a soil layer reinforcement area from the viaduct pile foundation, and construction of the viaduct pile foundation, a bearing platform and a viaduct pier stud is conducted; according to the viaduct construction method for underlying tunnel protection, the tunnel structure and the overlying stratum can meet the requirements for viaduct construction and operation, the design is scientific and reasonable, the steps are easy to operate, safety and reliability are achieved, the bearing requirement of the underlying tunnel can be met, and the purpose of reinforcement is achieved.
本发明公开了一种涉及到下伏隧道保护的高架桥施工方法，涉及地层加固和高架桥施工技术领域，包括计算高架桥桩基传递到土层加固区的荷载，在下伏隧道原有的钢筋混凝土衬砌内加固20～40mm厚钢环衬砌，提升下伏隧道承载力，对隧道上方土层进行地面注浆加固，土层加固强度满足高架桥桩基传递到土层加固区的荷载要求，进行高架桥桩基、承台和高架桥墩柱的施工；本发明涉及到下伏隧道保护的高架桥施工方法，使得隧道结构及上覆地层能够满足高架桥施工及运行的要求，设计科学合理，步骤容易操作，安全可靠，能够满足下伏隧道的承载要求，达到加固的目的。
