This paper has made a deep study of the application of the KUZ-RAM digital analogue in the dam materials lumpiness gradation analysis, and has proposed the procedure and method of establishing and modifying the KUZ-RAM digital analogue based on the dam material quarrying tests made for the Zipingpu Water Conservancy Complex Project.

On the Stuffing and Construction of Graded Gravel for Transition Zone in the High Speed Rail Bridge;

Through a great many of field experiment and comparison, we get economic, rational graded gravel and the mix ratio for bedding facing, work out a full set of constructional process plan, and quality control and check procedure.

The transition section graded broken stone construction technology;

The quality control points of graded broken stone foundation;

Analysis of continuous dynamic monitoring on vibrating compaction process of graded broken stone;

Characteristics of the modulus and distortion of the graded aggregate material;

Working performance and evaluation index of fly-ash graded aggregates

At the same time, the structure( 5cm asphalt pavement surface + 15cm graded aggregate.

Rational range determination of key sieve pores for graded crushed stone based on shear performance;

Improvement suggestions of automatic production line of graded crushed stone;

Construction of graded crushed stone construction of the surface layer of subgrade bed of Jiaoji passenger dedicated railway
