Abstract: Pile foundation was used in the conservation building of YingTianMen archaeological site of Luoyang City of Sui and Tang Dynasties. The pile cap was set to support the upper inclined column frame. As the site could not be excavated, the prestressed tie rod between foundations was constructed by underground excavation and pipe jacking technology to balance the horizontal thrust between foundations. The composition of the prestressed tie rod were introduced, the number of prestressed tension, the proportion and sequence of prestressed tension, the horizontal displacement control target of pile top and other design principles were introduced successively, as well as the construction scheme and construction control method of the prestressed tie rod were introduced. According to the comparison of construction monitoring and construction simulation results, the construction scheme was adjusted. The results show that the horizontal displacement of pile top meets the established target during construction, and the variation trend is consistent with the construction simulation results. 

Keywords:YingTianMen archaeological site of Luoyang City of Sui and Tang Dynasty； archaeological site protection； underground excavation and pipe jacking； prestressed tie rod； construction monitoring
