the problem that the existing methods can not directly
conduct on-site real-time observation and research. The
internal structure and morphological characteristics of
soil-rock mixture can be reconstructed, which solves
the problem that the traditional method cannot directly
reconstruct the in-situ soil-rock mixture. The reconstructed
image of the internal structures obtained by
this method is based on the actual measured image data,
which should be more accurate and reliable in theory
compared with the numerical simulation method.

structure of in-situ soil-rock-mixture. We built an ultrasonic
transmission imaging experimental system and a visual detection
method sensitive to the morphological characteristics
of the internal structure of soil-rock-mixture. The main conclusions
are as follows:
◗ An ultrasonic probe sliding fixing device was constructed.
The ultrasonic probe can be fixed on any part of the soilrock
mixture in an adaptive and telescopic way, and can
be freely rotated and telescopic in a 360-degree circular
direction. The fixed observation of any probe size can
be realized. It is convenient for the multi-directional and
multi-angle ultrasonic imaging detection and engineering
application analysis of the morphological characteristics
of the internal structure of soil-rock mixture.
◗ The visualization observation and real-time ultrasonic
imaging detection of the internal structure and morphological
characteristics for in-situ soil-rock mixture can be
realized, which is more convenient and simpler than the
traditional indoor MRI methods and optical methods. A
new method of analyzing and calculating the pore space
ratio of soil-rock mixture can be realized by using the
profile image obtained by the ultrasound imager, which
is intuitive and visual with good real-time performance.
◗ The contact state of the internal structure of soil-rock
mixture can be observed and analyzed, which solves
