With the characteristics of high efficiency and economy, pre-stress anchorage technology is widely applied in all sorts of rock and soil reinforcement engineering. The opposed pre-stress steel bar reinforcement was used in 2# abutment of Gaojiazhuang. In the construction process, temporary reinforcing measures were used to ensure the abutment steady. Based on the analysis and discussion on the engineering practice, the construction procedure and methods were studied and summed up.
