摘要
Abstract
Tuanhe aqueduct, one of the large river-crossing buildings on the main canal of Middle Route Project of South-North Water Diversion, passes through the Tuhanhe River and was planned to be constructed in two phases during dry season. In order to realize the completion target of principal works by the end of 2013, the construction of 16 pre-stressed aqueduct bodies of No. 2~5 sections, located at main channel near right bank of Tuanhe River, was advanced to flood season of 2013. With con-sideration of the changes in current hydraulic conditions, hydraulic calculation and analysis for the construction of two-span steel platform scheme during flood season were carried out. The results showed that the protection scope for the riverbed under the steel platform ranged from 35m upstream of axis to 50m downstream while the toe protection width of bank-head on both sides was 10m.关键词
