Aimed at the shortage of traditional wetlands conformation,this paper optimized the Subsurface Flow Wetlands(SFW),advanced a new kind of wetland——Wavy Subsurface Flow Constructed Wetlands with contractive section and distributing system by stages.

Analysis and Calculation of Reinforced Concrete Shrinkage;

The cause for volumetric shrinkage and warpage was ana- lyzed.

In order to study the early-age cracking tendency of high strength concrete under circumfer-entially restrained condition, the non-contact shrinkage measuring device was developed to determine the free shrinkage of high strength concrete with water to cement ratio of 0.
