摘要:
桩基础由于具有承载能力高、抗震性能好等优点在工程中得到广泛使用,但同时,桩基础作为隐蔽工程,施工质量也难以很好控制,由于桩基质量低劣而引发的工程事故时有发生.因此,提高桩基检测分析水平,查明桩内缺陷是工程安全与耐久的前提.在现有超声波测桩分析方法中,还没有充分考虑不同程度的缺陷对超声波声速、频率和振幅的影响,相应的判断缺陷的方法比较笼统.鉴于此,利用抽样分布定理求出超声波声速、频率及振幅的期望和方差的置信区间,并在此基础上给出超声量属于"好"、"-般"、"差"的隶属函数,用模糊综合评判的方法对超声波检测桩
Abstract:
Pile foundation is widely used in engineering due to its advantages of high bearing capacity and good seismic performance, but at the same time, as a hidden project, the construction quality of pile foundation is difficult to control well, and engineering accidents caused by poor quality of pile foundation occur from time to time. Therefore, improving the level of pile foundation detection and analysis and identifying the defects in the pile is the premise of engineering safety and durability. In the existing ultrasonic pile analysis methods, the influence of different degrees of defects on ultrasonic sound velocity, frequency and amplitude has not been fully considered, and the corresponding methods for judging defects are relatively general. In view of this, the confidence intervals of the expectation and variance of ultrasonic sound velocity, frequency and amplitude are obtained by using the sampling distribution theorem, and on this basis, the membership functions of "good", "-general" and "poor" of ultrasonic quantity are given, and the ultrasonic detection pile is tested by the method of fuzzy comprehensive evaluation
