The invention discloses a method for forming an anti-sliding vibro-replacement gravel pile under an ultra-deep covering layer of an ultra-strong seismic zone. The method comprises the steps that holes are formed in a stratum clamped with a high-viscosity sliding layer to form gravel pile holes; during hole cleaning treatment, the lower water flow and the lower gas flow are controlled according to the slurry density information; the gravel pile hole is filled with materials for vibroflotation and densification construction, specifically, a vibroflotation device conducts vibroflotation and densification on the gravel materials put into the pile hole located below the slippage layer, and a lower gravel pile section is formed; the vibroflot carries out vibroflot on the filler thrown into the pile hole corresponding to the slip layer, the filler is vibroflot into the slip layer around the gravel pile hole, then the thrown gravel filler is vibroflot densified, and a slip layer gravel pile section is formed; afterwards, the vibroflot continues to conduct vibroflot densification on the gravel filler put into the gravel pile hole, and an upper gravel pile section is formed. The vibro-replacement gravel pile formed through the method is good in water permeability, the pile diameter meets the requirement, and the vibro-replacement gravel pile cannot be dislocated under the strong shock condition.
本发明公开一种超强地震带超深覆盖层下形成抗滑移振冲碎石桩方法，包括：对夹有粘度较高滑移层的地层进行造孔以形成碎石桩孔；清孔处理期间，根据泥浆密度信息控制下水流量和下气流量；向碎石桩孔内填料进行振冲加密施工：振冲器对投放到位于滑移层下方的桩孔内的碎石填料进行振冲加密，形成下方碎石桩段；振冲器对投放到对应于滑移层的桩孔内的填充料进行振冲，将填充料被振冲到碎石桩孔周围的滑移层中，然后对投放的碎石填料进行振冲加密，形成滑移层碎石桩段；之后，振冲器对投放到碎石桩孔内的碎石填料继续进行振冲加密，形成上方碎石桩段。本发明方法形成振冲碎石桩透水性良好，桩径符合要求，能在强震条件下不发生错断。
