Discussion on the cross section types of high piers of bridge and stability calculation;

The paper introduces the manufacture and the model for stability calculation of the GFRP(Glass Fiber Reinforced Plastic) supporter of pneumatic roofborer, and provides scientific basis for opimum design of the supporter.

Based on the analysis of failure mode and stability calculation at Da-Gu Jian of Zi Gui town in Hubei province,it is possible that the high slope falls along the bed rock surface or collapses by soil mass.

Direct calculation method for stability design of circular cold-formed thin-wall steel tube under axially compressive force;

In the stability design of the bottom slab of stilling basin or water cushion pool for a long time past, a little attention was paid to the pulse load on the slab.

Secondly,on the basis of elastic-plastic stability analysis,referring to the stability design method of monosymmetric section axially loaded compression members,equivalent slenderness of pin-ended circular steel arch subject to hydrostatic pressure are deduced from the expression of out-of-plane elastic buckling load.

Heuristic method approach to the computational stability analysis of finite-difference equations;

The computational stability of two kinds of general three time level schemes and two time level schemes are analyzed, a new method for judging the computational stability is given.

Based on the forced dissipative nonlinear evolution equations for describing the motion of atmosphere and ocean, the computational stability of the explicit difference scheme of the forced dissipative nonlinear atmospheric and oceanic equations is analyzed and the computationally stable explicit quasi complete square conservative difference scheme is constructed.
