Recently, a technical achievement of China Construction Communications Engrg. Group Corp. Ltd. (CSCEC Communications) was verified by Beijing Municipal Commission of Housing and Urban-Rural Development and recognized as a world advanced technology.
The research on key construction technique for rail transit projects in karst regions resulted in a whole set of techniques for prospecting, design and construction which are suitable for rail transit construction in karst areas. This technical achievement particularly includes methods for prospecting and hole distributing subway projects in karst areas, determination of the reasonable range for karst treatment, comprehensive treatment of the 3D partition of the deep foundation pit of the subway in karst developing areas, and principles and requirements for selecting shield machine suitable for the earth pressure balance in karst areas.
The new technique has been widely used in many projects including the rail transit Line 2 in Nanning, and yielded remarkable social and economic benefits. (from CSCEC Communications)
