【摘要】 低应变反射波法具有快速、简便和费用低廉等优点,但同时又存在检测结论不全面、不定量,可靠性低等缺点;而钻芯法具有科学、直观、精确等优点,但它却存在速度慢、实施难、费用高等缺点。如果将两种检测方法巧妙地结合起来进行,既节约检测成本,又能可靠全面地反应钻孔灌注桩桩身质量.

【Abstract】 The low-strain reflection method features efficiency,ease and low cost of test,but its weaknesses lies in incomplete test result,and being unable to quantify the result and low reliability.In contrast,the coring method has the advantages of being more scientifically acceptable,straightforward,and accurate.Yet its weaknesses are found such as low speed,difficulty with implementation and high cost.It is believed that combining the two methods,however,may not only save the cost of test,but also on the whole reflect the quality of borehole cast-in-place pile.
