Construction technology and application of mixed pile;

Construction technology of cement-soil mixed piles;

The indoor formulation experimental analysis on reinforcement of soft soil foundation using mixed pile at Yan Tai pontoon base;

Construction of SMW mixing pile and its quality control;

Application of the cement deep-mixing pile in the overpass in Chenglu in Jiangyin city;

Study on behavior of soil-cement mixing piles of support structure considering soil layers;

Analysis of function of soil-cement mixing piles composite soil nailing by small pre-stress;

The paper analyses the behavior of soil-cement mixing piles in compound soil nailing support with 3D nonlinear FEM, and some valuable conclusions such as displacement, bend, shearing force, stress of soil-cement mixing piles with the staged excavation are obtained, which can be taken as references in design and construction of compound soil nailing.

Application of cement deep stirring piles in engineering;

And after checking computation and monitoring,we educe the design scheme that uses the stirring pile and jet grouting pile to form the gravity type retaining wall and waterstop curtain is feasible,in order to offer a reference for similar engineering.

By cement-stirring piles to consolidate the sea dyke and jet grouting piles to reinforcing the foundation of sea dyke revetment,the entire shear strength of the dyke and the embankment foundation soil mass will be enhanced so as to solve deep sliding and stability issues.
