碾压砼筑坝连续上升16m的施工经验

Dam Construction Experince of Continuous Placement of RCC by 16m High

碾压砼在我国是最近几年发展起来的一种新兴筑坝技术.本文总结了在铜街子工程进行的连续上升至16m高度快速施工经验,高块连续浇筑须具备的施工条件,核算通仓浇筑带来的温度应力问题,为了解高块连续浇筑的坝体温度及变形,布置了监测仪器,并总结了观测成果。

RCC Placement is a new dam construction technology developed in China recently. These paper sums up the experince for rapid and continuous placement of RCC by 16m high carried out at Tongjiezi project ,and poses the construction conditions which meet the requirements of contiuous placement of high monolith. The temperature stress araised by placement from one abutment to other was calculated. The monitoring instruments were embedded to see the temperature and deformation in the dam section which was placed high without stop,The instrumentation result were analyzed.
