Embodiment Construction

[0106] The method for comprehensively judging the detection data of foundation pile acoustic wave transmission method of the present invention comprises the following aspects:

[0107] 1. Adopt bilateral low and high value elimination method, the specific method is as follows:

[0108] (1) The sound velocity value V of each acoustic line of the jth detection section i (j) Sort in descending order, namely:

[0109] V 1 (j)≥V 2 (j)≥…V n-l (j)≥…V i-1 (j)≥V i (j)≥V i+1 (j)≥…V n-k (j)≥…V n-1 (j)≥V n (j)

[0110] (1-1)

[0111] Where: V i (j) - the sound velocity of the i-th acoustic line of the j-th detection profile, i is 1~n;

[0112] n-the total number of acoustic survey lines of the jth detection profile;

[0113] k-the data number of the low sound velocity value to be removed, k=0,1,2,...;

[0114] l-the data number of high sound velocity value to be removed, l=0,1,2,....

[0115](2) To remove V i Statistical calculations are performed on the rest of the data ...

Abstract

The invention relates to a foundation pile sound wave transmission method detection data comprehensive evaluation method, which is characterized in that (1), using dual-edge low-high value removing method to calculate sound parameter abnormal judgment critical value, comprehensively considering the normal ranges of the sound speed critical value and concrete sound speed of probability method, according to the bias degrees of the sound parameter detection value and the abnormal judgment critical value, making defect degree judgment standard, (2), using a sound test line to replace general test point to describe the sound parameters of sound wave transmission method, according to the physical character of different sound parameters and the data stability, making a standard for comprehensively evaluating the completeness classification of each sound test line in a detection section, (3), using the pile section as basic judgment unit to combine the completeness of each sound test line on the section to judge the completeness of each section, to evaluate completeness classification at the point of whole pile. The invention can effectively improve the objectiveness and scientific property of detection data analysis and processing, save material and human resource and improve significant social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of evaluation of detection data of foundation pile acoustic wave transmission method. Background technique [0002] The development of high-rise buildings, long-span buildings, and large-scale bridges all require to increase the bearing capacity of the foundation. The use of large-diameter cast-in-place piles can significantly improve the bearing capacity of single piles, and the comprehensive quality evaluation of large-diameter cast-in-place piles has always been a problem in the engineering field. problem. Compared with other methods, the detection of concrete pouring pile body defects by acoustic transmission method has distinctive features: the detection is comprehensive and meticulous, the range of acoustic wave detection can cover all cross-sections of the pile length, the amount of information is quite rich, and the on-site operation is simple and convenient. Quick, not limited by pile length and as...
