Studies of deformation structure in the eastern segment of the Altun fault zone indicate that it can be divided into the ductile sinistral strike-slip domain with subhorizontal stretching lineations (SS domain) and the contractional deformation domain with steeply plunging stretching lineations (PS).

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.

By use of digital camera to collect picture quickly and technology of computer to deal with picture, a new measurement method for residual contraction distortion after welding is introduced in this article.

The technology of injection molding of PP-R fittings was conditioned to reduce their shrinkage strain and to make PP-R fittings keep a good appearance and properties.

The shrinkage strain,crack length and width are measured when the shrinking of mortar becomes stable.

Some measures were taken in layout design and structural design to solve the shrinkage distortion problem of strip material during the drawing in a progressive die.

According to the cracks commonly produced in c as t-in-site reinforced concrete floor-slab, based upon detailed analysis the ca using reasons are pointed out, which mainly caused by shrinkage distortion, temp erature changes and construction factors.
