浅层地震仪检测水泥土搅拌桩完整性应用研究
|
摘要
水泥土搅拌桩因其价格便宜,施工便捷,被广泛应用于软土地基处理。而其质量检测,特别是无损伤检测一直存在技术问题。为此,本文对应用浅层地震仪检测水泥土搅拌桩完整性的理论及可行性进行了探讨。并用于某工程水泥土搅拌桩完整性评价,与抽芯检测结果对比表明,利用浅层地震仪检测水泥土搅拌桩的完整性是可行的。
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.
