The invention discloses a method for forming a permeable vibro-replacement gravel pile under an ultra-deep covering layer of an ultra-strong seismic zone. The method comprises the steps that gravel pile holes are formed; hole cleaning treatment is conducted on the gravel pile hole, and in the hole cleaning treatment process, a real-time ultrasonic signal corresponding to the density of mud in the gravel pile hole is obtained; according to the obtained real-time ultrasonic signal corresponding to the density of the slurry in the gravel pile hole, the water discharge flow of supplied water and the gas discharge pressure of pressure supply gas discharge are controlled; after hole cleaning treatment, gravel filler is put into the gravel pile hole, and vibroflotation densification construction is conducted through a vibroflotation device; and during vibroflotation and densification construction, vibroflotation and densification of the vibroflotation device are controlled according to the real-time electric signal corresponding to the amplitude of the vibroflotation device, so that the vibroflotation gravel pile with the effective pile diameter is formed. According to the method, it is ensured that the water permeability in the gravel pile hole meets the preset requirement, so that it is ensured that the ultra-deep vibro-replacement gravel filler pile formed under the ultra-deep covering layer of the ultra-strong seismic zone is good in water permeability, and the pile diameter meets the requirement.
本发明公开一种超强地震带超深覆盖层下透水振冲碎石桩形成方法，包括：形成碎石桩孔；对碎石桩孔进行清孔处理，且在清孔处理过程中，获取对应于碎石桩孔内泥浆密度的实时超声信号；根据获取的对应于碎石桩孔内泥浆密度的实时超声信号，对供应下水的下水流量和供压下气的下气压力进行控制；清孔处理后，将碎石填料投放到碎石桩孔内，利用振冲器进行振冲加密施工；振冲加密施工期间，根据对应于振冲器振幅的实时电信号，对振冲器的振冲加密进行控制，以形成具有有效桩径的振冲碎石桩。本发明方法，确保碎石桩孔内透水性符合预设要求，以便保证在超强地震带超深覆盖层下形成的超深振冲碎石填料桩透水性良好，桩径符合要求。
