| 摘 要： | 针对潮间带地区因大水力梯度交替变化的影响导致地基真空预压施工加固效果较差的问题,对塑料排水板打设、侧向密封系统及抽真空系统施工等方面的技术工艺优化进行研究。采用施工全过程监控方法进行验证,得出大潮差条件下开展真空预压施工的积极结果。结论显示,调整水平排水系统的滤管间距、增设双排淤泥搅拌桩作为侧向密封墙和调整真空泵布设方式等,能有效提升潮间带地区真空预压施工效果。

| Abstract: | The alternation of hydraulic gradients and high tidal range in the intertidal zone leads to the bad effect of foundation vacuum preloading,so we probe into the process optimization in fields of driving of the plastic drainage plate,and construction of the lateral sealing system and vacuum system.Verifying by the whole construction process monitoring,we obtain some positive results.The results show that the effect of vacuum preloading can be improved by adjusting the filter spacing of horizontal drainage system and adding double row sludge mixing pile as lateral sealing wall and adjusting the layout of vacuum pump. |
