万家寨低热微膨胀混凝土现场试验及观测成果分析

Field Test and Observation Data Analysis of Low-heat Micro-expansion Concrete of Wanjiazhai Water Control Project

万家寨水利枢纽采用低热微膨胀混凝土筑坝,该项目选择左岸低缆基础、上游纵向混凝土围堰等部位,对低热微膨胀混凝土进行了现场试验,并应用于工程的其他部位,获取了大量的观测资料,同时对观测成果进行了分析。对其他工程的应用具有一定的借鉴作用。

Low-heat micro-expansion concrete was applied to the dam of the Wanjiazhai Water Control Project. The field test for the low-heat micro-expansion concrete was carried out at the left bank foundation of the lower cable crane, the upstream longitudinal concrete cofferdam, etc. Such concrete was also used in other parts of the project. Large quantities of observation data are obtained and analyzed. The result is beneficial to the design of other projects.
