Soil w ater characteristic curve is one of the im portant graphs reflecting the fundam entalpropeties ofunsaturated soils, w hich is usually determ ined by the pressure plate test.

With the parameters of common soil laboratory test data,c,f,g,t-u,the defomation modulus Eo of foundation is established by the relation between Eo and N from plate loading tests.

Field pressure test of submarine pipeline system;

Fuzzy Reliability of the Static Strength of the Thin-Wall Internal Pressure Cylinders at Pressure Tests;

Reliability analysis of steel thin wall cylinder during pressure test;

Discussion on vessel flange intensity under the test pressure;

In this paper, by using reliability design methods, the test pressure of ultrahigh cylinder is studied.

It analyses stress sustained by pipe during hydrostatic test and briefly introduces calculation formula deduced process of test pressures.

This paper introduces the experiment condition of pressure experiment for water supplying pipeline of glass steel,experiment technology and method.

According to GB150-98 steel pressure vessel, it is proved that the horizontal cylinder under internal pressure needs no pressure testing for stress checking .

Because the single heat exchange tube has little volume, welding in series is always applied in pressure testing,but the impacting pressure will take place too.

Pressure vessels must make pressure testing before they are taken part into practice.
