The result indicated that it has better effect to evaluate rock quality with blurred information optimum seeking technique.(2) It is the first time that the interrelated relationship of the result of in-suit rockmass deformation test and fractal characteristic of structure on test point has been applied to determine rockmass deformation parameter. The question of evaluating deformation parameters of engineering rockmass has been solved.(3) Anisotropy strength parameters have been determined by applying shear zones simulating method. The result indicated that there are different strength parameters in every structural area, after comparing the result of Fast Lagranian Analysis in continua number simulation method with that of method of weighted mean according to continuity. The result indicated that when a suitable reduction coefficient is been considered rockmass strength parameters can be simply and fast determined with method of weighted mean according to continuity where there is not enough test result.(4) Damage characteristic has been studied based on analysis fractal characteristic of structural plane network by applying fractal-damage coupling method. It is the first time that the concept of damage degree has been set up to evaluate rockmass quality according to the biggest principal damage.

The measurement results of the bridge load testing experiment were heavily influenced by the field environment. Based on the field test results of strain which were affected by simulated outside temperature, it was proposed that the compressed enameled wire could replace the traditional rubberized wire and shielded cable in bridge load testing experiments. This was supported by abundant data collected from the in-situ measurements and the results of these measurements were positive. As bridge-arm lead in the electrical resistance strain testing system, the compressed enameled wire was more stable than the rubberized wire.
