Abstract:The rapid development of China water resources and hydropower projects has resulted in a vari-ety of demands of new technology. This paper focuses on three typical areas:(1) building deep walls up to 150m;(2) strengthening old dams and dikes suffering from heavy leaking, and (3) special technology for coffer dam seepage control. This paper gives a comprehensive review on the key technology of these ar-eas and the typical case histories. The highlights include:(1) innovative technology on slurry and drilling facility to construct walls as deep as 150 m;(2) special technology to form full barrier against seepage for old dams with high risk of piping potential, and (3) The coffer dam seepage control engineering meth-ods.
Keywords:super-deep diaphragm wall  strengthening of defective dams  coffer dam seepage control engi-neering  construction technology
