For concrete double-curvature arch dam at Baotan Hydropower Station,at tender stage and at constructional organization design stage one LSLGF100 water cooling unit is planned to be used separately to pre cool water used for concrete mixing in hot days from May to October.

The final scheme is concrete double-curvature arch dam,4 surface holes + 5 deep holes + 2 bottom outlets + plunge pool,and a flood discharge tunnel with pressure flow section connected to free flow section and underground power house on right bank.

Pre-splitting blasting technology for foundation excavation of high RCC double-curvature thin arch dam;

The excavation of the rolled concrete double-curvature arch dam and gravity dam in Dahuashui hydroelectric station in Guizhou adopted deep-hole graded slight differences demolition.

Risk analysis of construction progress of large concrete arch dam;

Reliability index calculation of concrete arch dam by a combined stochastic FEM and maximum entropy method;

Linear cracking stochastic analysis and nonlinear intension analysis of concrete arch dams;

Concentrated on the questions of temperature control and crack prevention studies on concrete of arch dams, simulative calculation theories of temperature and stress fields of concrete of arch dams are systematically studied in theory and practice, the temperature control of Huaguangtan arch dam is analyzed and studied in detail.
