高频振动沉桩对周边环境的影响
Influence of High-frequency Vibration Pile-driving on Surrounding Environment
摘要
Abstract
Relying on the engineering case of high-frequency hydraulic vibration pile-sinking in the reconstruction project of Kunming Textile Factory in Yunnan province, through on-site investigations, indoor geotechnical tests and three-dimensional dynamic finite element numerical simulation based on Midas GTS NX, the influence of high-frequency vibrating pile-sinking on surrounding environment of the steel tubular pile is analyzed. The analysis is performed in the aspects of excitation frequency, pile diameter, excitation force and soil conditions. The results show that the lower excitation frequency of pile sinking has the greater influence on the surrounding environment. Within a certain area around the steel tubular pile, the smaller pile diameter, the larger vibration force and dynamic elastic modulus of soil can lead to greater influence on the surrounding environment. Finally, according to the research results, the engineering measures to reduce the environmental impact of vibrating pile sinking are proposed.关键词
