Abstract

The invention provides a dynamic compaction treatment based liquefaction computing method. The method comprises the steps of obtaining construction parameters and soil body parameters; simulating dynamic compaction liquefaction, analyzing the influence of the parameter change on the liquefaction range, obtaining respective normalization coefficients, and computing liquefaction range normalization coefficients corresponding to the parameters on site by utilizing an interpolation method; substituting the liquefaction range normalization coefficients into a liquefaction coefficient computing formula to obtain liquefaction coefficients, and computing a soil body liquefaction range; and according to the liquefaction range values at multiple moments, analyzing liquefaction characteristics of a soil body and optimizing dynamic compaction construction layout. According to the dynamic compaction treatment based liquefaction computing method provided by the invention, based on a large amount of experiments and simulation verification, a normalization coefficient table is summed up and the liquefaction computing formula is proposed, so that the liquefaction characteristics of the construction parameters are determined and reasonable dynamic compaction construction arrangement can be conveniently provided; and the method has the advantages of simplicity, high efficiency and the like, and especially has extremely high accuracy when the problem in saturated soil liquefaction is solved, thereby having wide engineering application prospects and high practicality.

Description

technical field [0001] The invention relates to the technical field of dynamic compaction construction in saturated sandy and powdery foundations, in particular to a liquefaction calculation method based on dynamic compaction processing. Background technique [0002] Dynamic compaction is a traditional and very practical foundation reinforcement treatment method. It is the convenience and practicality of dynamic compaction. From ancient times to the present, dynamic compaction has been widely used in engineering practice. Especially since the reform and opening up, my country's urban construction has developed rapidly, and a large number of various projects have sprung up, such as: dams, ports, skyscrapers, residential buildings and industrial plants. With the development of these projects, the requirements for foundation treatment technology and construction efficiency are getting higher and higher, and the commonly used dynamic compaction method is also constantly developi...
