In order for the level of roads renovated according to Luping Project to be as originally designed, it was required that new road building concepts be adopted for design and construction when handling road renovation engineering.
The road sections treated each year must be integrated in the previous year with construction plans, such as replacement of tap water pipelines, improvement of duct nets of sanitary sewers or underground electric poles engineering of electric power lines, with each pipeline unit to prevent from re-excavation after completion of Luping Project construction.

Studies have shown that, TMD system has a good effect for reducing vibration caused by dynamic load with long period or narrow band, and the application prospect is very broad in civil engineering[3].
Based on long-term research on vibration technology and much engineering experience, Chinese scholars, independently develope a new type of stiffness adjustably tuned mass damper[4], which makes TMD vibration control technology applied in several large projects of our country, such as the Beijing Olympic Park National Convention Center[4], Changsha new railway station[4], Qingdao North Railway station[5].
Modal parameter of vertical acceleration time-history data of boarding bridge collected by vibration pickup are identified by Jiangsu Anzheng Software Engineering Co.
