Study on the integrity of measuring cement mixing pile with seismograph
Guo Jun-hu · 2010
Because of cheap price and convenient construction,the cement-soil mixing pile is widely applied in weak soil region foundation treatment.But for a long time,there are many problems in the ways of quality detection,especially in the nondestructive detection.For this reason,measuring integrity of cement mixing pile with shallow seismograph is put forward.The theory and feasibility of this way is discussed in the paper.And this way is used in the integrity assessment of cement-soil mixing pile in a project.The comparative analysis with the results of Core-Pulling shows that using the shallow seismograph to measure the integrity of cement-soil mixing pile is completely feasible.
