论碾压混凝土坝上游面喷丙乳砂浆的防渗作用

碾压混凝土具有施工速度快，水泥用量少，投资省等明显的优点。国内的理论研究和工程实践都取得了突飞猛进的进展，在防渗问题方面也进行了卓有成效的探索，如福建省几座已建成的碾压混凝土坝均采用不同的防渗类型。文章结合福建省重点工程连江山仔水利枢纽工程碾压混凝土坝的施工情况，介绍了能够充分发挥碾压混凝土坝快速施工特点的悬臂钢模、改性混凝土的施工方法，论述了喷丙乳砂浆作为碾压混凝土坝上游主防渗体与这一施工特点相统一所具有的优越性。

Study on Seepage Control Function of Spraying Acetone Resin Emulsion Mortar on the Upstream Face of Roller Compacted Concrete Dam (RCCD)

The roller compacted concrete has many obvious advantages of speed construction, less cement consumption and saving capital cost.The progress have been achieved in theory study and engineering practice in our country. The effective studies are also produced in seepage control of dam. For example, The various seepage control measures are practised in Fujian Province. The construction method of cantilever steel formwork and modified concrete of speeding roller compacted concrete dam construction are introduced by a case, construction of roller compacted concrete dam of the Lianjiangshanzai hydraulic project of Fujian Province in this paper. The advantage of main seepage control body of spraying acetone resin emulsion mortar on upstream face of roller compacted concrete dam is also been explained.
