An accurate description of the load transfer behaviors geosynthetic-encased stone column (GESC) is great importance for revealing bearing capacity GESC. Static tests and shake table model were performed to characterize static dynamic composite foundation reinforced by Under loading, conducted on a fully (FGESC), partially (PGESC) traditional (TSC). The influence length stiffness encasement colu...

This paper mainly uses the method of model test to study ultimate uplift bearing characteristics a single pile with different length-to-diameter ratios, from distribution laws capacity pile, axial force and side friction perform analysis. The is made PVC pipe, resistance strain gauges are attached both sides pipe. value pipe under load conditions measured obtain working behavior during process ...

In order to investigate the force characteristics of occlusal pile, this paper takes underground garage support project Nanchang Bayi Square as research background and studies bending moment pile after excavation process foundation pit through model test. The test results show that increases then decreases with increase soil depth under horizontal load, reaches maximum near surface pit; can pro...

At present, reducing subgrade settlement of soft soil foundation is a key problem in high-speed railway construction. Pile-slab structure is a widely-utilized form of foundation structure to reduce the subgrade settlement in China. In order to save the engineering cost for high-speed railway construction in developing countries, the author developed a pile-slab structure and named it as the new...

Root piles are injected and installed during mortar shaft construction, using pressures of up to 500 kPa. The executive control is typically done through static load testing, an expensive time-consuming method. Static tests on eight controlled (diameters between 310 mm 410 mm) were performed, aiming at evaluating pile ultimate load. This study suggests innovative, non-destructive approach valid...

Pretensioned prestressed high strength concrete (PHC) pipe piles are widely used in various engineering foundations, which have the advantages of single pile bearing capacity, strong adaptability to geological conditions and degree construction mechanization. In order study vertical compressive performance settlement characteristics ultra-long PHC piles, strain dynamic detections static load te...
