The top depth of upper mantle and deep tectonic characteritics in Northeastern China is studied in this paper by means of the Bouguer gravity anomaly map With the ratio of one to a million.

Analysis of radius and depth of shield tunnel on its seismic response

Same as the burial depth,the burial time also has great effect on the evolution of porosity of the classic rocks during compaction,which is clarified by three aspects in this paper.

Based on the vertical sealing mechanism of a fault, by analyzing the relation between the pressure form overlap sedimentary load, distribution conditions of mudstone deformation characteristics of mudstone in fault zone and depth, this paper studied the vertical sealing characteristics of a fault in section.

The relationship in drainage pipeline size and buried depth and the technical measure for controlpoint;

Calculating buried depth of transverse sills for the debris flow drainage groove with soft foundation

The multi-polar coordinate,complex function and stress wave theory are employed to study the influence of buried depth on critical vibration velocity of circular cavity induced by blasting vibration,a circular cavity with large radius is used to replace the straight boundary of the half space.
