中科院武汉岩土力学所王靖涛运用应力波理论和低应变法完成了桩基完整性快速定量分析程序WANG-PIP和承载力计算程序WANG-PCP。“WANG-PIP”可对桩基完整性作出定量分析,估算出桩身断裂或扩缩颈的严重程度,并由此对桩身完整性作出分类。对轻微损坏的桩可不必完全抛弃,从而既保证了工程质量,又避免了浪费。它保持了低应变法简单、迅速、成本低的特点,同时又可获得定量的结论,是低应变法的一个重大发展。
Wang Jingtao, Wuhan Institute of Rock and Soil Mechanics, Chinese Academy of Sciences completed the rapid quantitative analysis program WANG-PIP and the bearing capacity calculation program WANG-PCP of the pile foundation using the stress wave theory and the low-strain method. “WANG-PIP” can quantitatively analyze the integrity of the pile foundation, estimate the severity of the pile breakage or neck expansion, and thus classify the pile integrity. It is not necessary to completely discard piles that are slightly damaged, thus ensuring both the quality of the project and avoiding waste. It maintains the low-strain method’s simplicity, speed, and low cost. At the same time, it can obtain quantitative conclusions. It is a major development of the low-strain method.
