Seismic engineering geological problems of various sites and ground soil in Tangshan earthquake, July 28, 1976, are systematically analysed in this scientific research problems are discussed specifically in five aspects: seismic fracture, Seismic liquefaction, ground movement, earthquake damage analysis and compiling of seismic engineering geological maps. Furthermore, formation mechanism and distribution routine of various damaging effects are also studied in view of site condition and engineering geological problems to be encountered during the reconstruction of Tangshan city. Engineering aseismic criteria and measures for foundation treatment in different site condition are submitted.
