1. A determining device for the weathering resistant capability of clastic rocks in a tunnel based on feldspar features, comprising:
a sampling mechanism, mounted in front of a TBM to obtain rock block or/and rock powder samples of a tunnel face;
an automatic scanning module, configured to collect omni-directional images of a rock stratum before the samples are obtained;
an element analysis module, configured to collect the information about basic chemical elements included in the samples;
a microscopic image module, configured to extract cleavage features, interference color features, relief features and crystal structure features of feldspar in the samples;
a wireless transmission module, configured to transmit data obtained by the automatic scanning module and the element analysis module to a data analysis center; and
the data analysis center, configured to, according to the obtained information, obtain cleavage information and crystal structure information by extracting image features and element features, and then determine a grade of weathering resistant capability of the rock stratum.
