Determination of embedding depth of abrasive grains on working surface of single-layer brazed CBN grinding wheel;

The cutoff value of net pay depends greatly on the component texture, fluid property (especially, crude oil property) and buried depth.

Empirical tangent method for reservoir depth estimation has been put forward by studying a relation between apparent-resistivity abnomal width and oil reservoir depth.

The result of analysis shows that the magnitude of in situ stress has the trend to increase with the increasing of the depth and the elastic module of rock mass,but the relation between the in situ stress and elastic module is not so close as the relation between the in situ stress and depth.

The paper mainly discusses embedded depth of foundation,partial fixing of Superstructure Construction,constraint action of backfilled soil and loads of basement based on the complexity and variety of structure model of High-Rise basemen.

This article aims to study how single-screw anchor works in sand through indoor test,gives the calculation formula of critical embedded depth and provides theoretical basis for the instruction of engineering practice.

Based on the stability analysis of large caisson foundations in Sutong Bridge, this paper represented that if the bearing capacity requirement on the caisson foundation base is satisfied, it is not true that the embedded depth of the caisson foundation is the larger the better, and the depth needs not to be large.
