Based on the Western Transportation Construction Science and Technology Project—“Evaluation on Wenchuan Earthquake Highway Damage Assessment, Mechanic Analysis and Fortification Standard”, the book records, analyzes and studies in details the highway subgrade damages of Wenchuan Earthquake, providing basic materials for studies on the seismic resistance capacity of highway. The book consists of nine chapters, covering overview of highway subgrade earthquake damages, statistics of Wenchuan Earthquake highway damages, subgrade damages of G213 from Dujiangyan to Yingxiu, subgrade damages of G213 from Yingxiu to Wenchuan, subgrade damages of G213 from Wenchuan to Maoxian, subgrade damages of S303 from Yingxiu to Wolong, subgrade damage of IX~XI area highway, subgrade damage of VII~VIII area highway and subgrade damage of VI area route.
As the valuable historical data and research materials, the book provides reference for the relevant researchers and concerned people.
Chen Lesheng, Chief Engineer of Sichuan Provincial Transportation Department, engaged, for years, in survey, design and construction of highways, bridges and tunnels and recently focusing on seismic research in highways of Wenchuan Earthquake.
