The application of the sandy pebble fillings in highway roadbed;

Analysis was made on sandy pebble replacing foundation in the character of vibrating compression,bearing capacity of sandy pebble ground and its function.

Foubdation treatment of changing and filling with sandy gravel large area;

Fractional structure of granularity distribution of natural sedimentary sandy gravel;

On the basis of analyzing the geological feature of sandy gravel,we research the problems of lacking fidelity on prospecting,non-defining properly the pile capacity on design and non-constructing according to standards on construction,use the major-diameter manual piles in this kind of layer and point out the measures we should use in prospecting,design and construction.
