Abstract
The construction of the bulkhead of the diversion tunnel for a water control project has the characteristics such as short construction period,more working intensity,long period of construction under the subzero temperature and difficult to lower temperature naturally;for which the control parameters for the construction of the bulkhead are properly increased compared with the original design values after the careful analysis and demonstration concerned.The monitoring data show that the concrete of the bulkhead has a better operation behavior to satisfy the requirement on its designed function,and then has a certain reference value for the bulkhead of the hydraulic tunnel within the similar region.
