【摘要】 目前的低应变法无法检测预应力混凝土长管桩的长度。本文利用平行地震法和磁法检测预应力混凝土长管桩的长度,取得了较为一致的结果。表明联合平行地震法和磁法在实际工程中应用是有效而可行的。更多还原

【Abstract】 At present,low strain integrity testing can not detect length of prestressed concrete long Tube piles.According to seismic wave velocity and attenuation coefficient differences of the soil and the pile,use parallel seismic method.Make use of the magnetic field intensity differences of the shaft and the end of the pile to use magnetic.In practical engineering use this two kinds of methods,achieve consistent results,showed that the parallel seismic and magnetic detection the length of prestressed concrete long Tube pile to be effective.更多还原
