A new apparatus based on the transient two hot-wires method and data acquisition system was constructed for absolute measurements of the thermal conductivity of liquids and gases and of pure fluids and mixtures.

Based on about 700 days creep experiment of RC beams,long-term deflection of cracking RC beams were predicted by meaning of bilinear method,a program was compiled,the results fit the test data nicely,and analyzed parameters which affect long-term deflection of members,the method used in the paper is c.

There are many methods of scaling pictures,the common of which are snapshot method,average method and bilinear method.

Single-line method and double-line method were adopted respectively to carry out uniaxial compression test on undisturbed loess (Q3) in the case of moistening or demoistening.

Single-line method and double-line method are adopted respectively to carry out uniaxial compression tests on undisturbed loess(Q3) in the case of moistening or demoistening.

Aiming at the problems occured in the engineering application about the double-line method of collapsibility test of loess, a correction is given in the paper, striving for the unification of the collapsibility indexes of loess, and providing accurate and resonable testing data for practical engineering project.

Forecasting ultimate bearing capacity of single squeezed branch pile by hyperbola method;

The ultimate bearing capacity of the single screwed pile was predicted based on the six piles with screws from four different sites by hyperbola method.

When the fracture load was not reached for a trial pile, the ultimate load of the pile might be predicted according to the field-surveyed load settlement data of existing trial piles and by P-S curve extension method and hyperbola method, among which, the P-S curve extension method had better adaptability.
