Involving numerous components of geological engineering, geotechnical engineering and tunnel engineering, this ebook describes the tender soil deformation features and dynamic responses triggered through subway vibration load. in response to box tracking and laboratory checking out facts, with either accomplished micro-and macroanalysis, the authors current dynamic features and deformation payment of saturated gentle clay surrounding subway tunnels utilizing dynamic and static method. Mechanism of deformation, failure in microstructure of soppy clay soil, dynamic reaction, macro deformation and cost are all mentioned and analyzed completely and systematically. a number of the examine findings during this booklet were generally utilized by means of huge subway businesses and may have broader program customers in destiny. all of the above make this publication a useful reference not just for technical engineers operating in subway layout or development but additionally for complex graduate scholars. Prof. Yiqun Tang works on the division of Geotechnical Engineering, Tongji collage, Shanghai, China.

1985, 1987) comprehensively discussed factors such as total load, loading period, load increment ratio, loading form, degree of cementation, and number of loading cycles influencing the deformation on clay. It was found that consolidation deformation under cyclic load was larger than that generated in static load, in which he elucidated the reason was secondary consolidation that occurred when the cyclic load was applied. And the corresponding amount in secondary consolidation was directly proportional to cyclic load value, load increment ratio, loading period, and organic content.
The variation of pore size distributions, porosity, and other pore structure parameters were derived by MIP, and pore structure characterization was described by SEM images. Hereby, the relation of macro-mechanical behavior was explored based on the microstructure parameters. 4 Numerical Simulation Numerical simulation model was established based on the field and laboratory tests. The dynamic response properties of soils around subway tunnel were simulated by a three-dimensional finite element model.
