Pile testing method for determining displacement rate of compacted gravel pile through porosity ratio
The invention discloses a pile testing method for determining the displacement rate of a compacted gravel pile through the porosity ratio. According to the pile testing scheme, the minimum displacement rate of the pile is rechecked through the change of the porosity ratio before and after pile testing of soil between piles; the stress state of the soil between the piles is simulated, consolidation test on the soil between the piles under the same condition is achieved, the consolidation degree of the soil between the piles is mastered through void ratio test, and therefore the replacement rate of the compacted gravel piles is effectively determined before formal construction of the pile foundation. According to the method, the displacement rate of the compacted gravel pile can be accurately determined before formal construction of the pile foundation.
本发明公开了一种通过孔隙率比确定挤密碎石桩置换率试桩方法，该试桩方案通过桩间土试桩前后孔隙比变化，复核桩的最小置换率；模拟桩间土受力状态，实现对桩间土进行同条件固结试验，通过孔隙比测试掌握桩间土的固结程度，由此实现桩基正式施工前有效确定挤密碎石桩置换率。该方法能够在桩基正式施工前准确的确定挤密碎石桩置换率。
