Importance: Cracks and ruptures at face slabs had appeared in several high CFRDs in the two decades before 2007.Some were with high leakages (> 1,000 liter/s) such as in Barra Grande (185m, Brazil) and Campos Novos (202 m, Brazil) both in 2005 , Mohale (145m, Lesotho) in 2006, Tianshengqiao 1 (178m, China) during reservoir impounding in 2003 and 2005, that means after 3 and 5 years of operation and Aguamilpa (187m, Mexico) and so on.
Importance: How to treat the cracks at face slabs?
It is a common concern.
We introduce the measures to treat the cracks at china CFRD which are the practical experiences.

1. Present status of foreign investment in China
In the first quarter, 2011, China actually used foreign investment of $30.34 billion, an increase of 29.4% compared to the same period a year earlier. Among them, the actual use of foreign capital in March is 12.52 billion US dollars, increased by 32.9% compared to the same period a year earlier.
China's foreign investment profit margins have been 20% or so, a very profitable for investors.
Editor's note: This technical book focuses on the design and construction of CFRD in China taking the Shuibuya CFRD of 233m in height as example. It summarizes the all-round experiences of the design, construction, supervision and construction management of CFRDs with all drawings and data in details. It is good reference and value technical manuals for dam builders.
