The invention discloses a method for forming a vibro-replacement gravel pile with an effective pile diameter under a super-strong seismic zone. The method comprises the steps that a detection element used for detecting deflection parameters of a vibro-replacement device is installed on a shock absorber or a guide rod; a pipeline used for supplying sewage penetrates through the vibroflot and then extends out of the bottom end of the vibroflot; in the vibroflotation construction process of the vibroflotation device, the perpendicularity of the vibroflotation device is controlled according to the vibroflotation device deflection parameters detected by the detection element; when the perpendicularity of the vibroflot reaches a specified perpendicularity range, the vibroflot controls the flow of supplied sewage according to the current stratum compactness to carry out vibroflot pore-forming construction; and after pore-forming construction is completed, the vibrator carries out vibro-replacement on the gravel filler put into the gravel pile, and the vibro-replacement gravel pile with the effective pile diameter is formed. According to the method, the vibroflot can accelerate vibroflot construction on the deep and thick covering layer stratum with the thickness being 50 m or above according to the stratum condition and the perpendicularity meeting the requirement, and the gravel pile formed by vibroflot gravel filler is tightly combined with the soil layer.
本发明公开了一种超强地震带下形成有效桩径振冲碎石桩的方法，包括：将用于检测振冲器偏斜参数的检测元件安装在减震器或导杆上；将用于供应下水的管道穿过振冲器后从振冲器的底端伸出；在振冲器进行振冲施工过程中，根据检测元件检测到的振冲器偏斜参数对振冲器垂直度进行控制；在振冲器垂直度达到规定的垂直度范围时，振冲器根据当前地层密实度控制供应的下水的下水流量进行振冲造孔施工；在造孔施工完成后，振动器对投放到碎石桩中的碎石填料进行振冲，形成具有有效桩径的振冲碎石桩。本发明方法，使振冲器能根据地层条件及符合要求的垂直度对50m以上深厚覆盖层地层加速振冲施工，并使振冲碎石填料形成的碎石桩与土层紧密结合在一起。
