Abstract

The embodiment of the invention discloses a pile bottom karst detection method, device and system, electronic equipment and a storage medium. The pile bottom karst detection method comprises the following steps that: a detection signal received by a receiving unit in a first direction in a phased array is acquired; a detection signal received by a receiving unit in a second direction in the phased array is acquired, wherein the second direction is perpendicular to the first direction; the propagation duration of the propagation of the detection signal from a transmitting unit to a pile bottom and from the pile bottom to the corresponding receiving unit is acquired; and a detection result of pile bottom karst is determined according to the amplitude of the detection signal reaching the receiving unit and the propagation duration. In this way, based on high-coverage detection data collection, accurate detection of a pile bottom karst situation is achieved.

Description

technical field

[0001] The invention relates to the field of geotechnical engineering investigation, in particular to a pile bottom karst detection method, device and system, electronic equipment and a storage medium. Background technique

[0002] The target of pile bottom karst detection is mainly the karst concealed in the bedrock. Its size and spatial development range are extremely complex. From the perspective of plane distribution, it is difficult to ascertain its spatial range by point instead of plane, which is likely to cause serious damage during the actual construction process. Unfavorable conditions such as rock-socketing on half of the pile foundation occurred in the process. Existing pile bottom karst detection methods mainly include advance drilling method, tube wave detection method, and cross-hole elastic wave method. Single advanced drilling is easy to miss karst, and increasing drilling will greatly affect the construction period. The tube wave detection...
