Based on in－situ data， this paper has dealt with the rock－socketed part as a three－dimension sys－tem， and analysed its load transfer behavior． The method for determining parameter K has been proposed．Preliminary discussion about load transfer of rocksocketed pile has been conducted

This article reviews the methods of modifying polyaniline with alkyl and aryl and preparing block and graft polyaniline copolymers,and briefly summarizes application potential of polyaniline.

This paper introduces the process of making the block type nonionic surfactant and the applications in the textile industry, cosmetics and other areas.

All thirteen excavation stages of a super deep foundation pit braced by rock-socketed diaphragm wall are simulated in this article using Drucker-Prager soil model and contact algorithm based on direct control method.

Combined with the large-diameter cylindrical rock-socketed continues diaphragm wall engineering fact,analysed and contrasted the deformation characteristic of the large-diameter cylindrical rock-socketed con- tinues diaphragm wall and the non-rock-socketed continues diaphragm wall by introducing three-dimension elas- to-plastic FEM and road-test method.

Batter piles adopt rock-socketed piles ofφ1.

These methods included combination piles with I shaped steel and PHC pipe, small steel pipe guiding, information construction and so on, successfully solved such problems as embedding depth, rock pressing, broken piles and so forth and got better effects.
