Method for evaluating chemical stability of pyroxene microcrystalline glass solidified body under multi-field coupling

The invention discloses a method for evaluating the chemical stability of a pyroxene glass-ceramic solidified body under multi-field coupling, which comprises the following steps of: taking a plurality of pyroxene glass-ceramic solidified body samples with the same specification as parallel test objects, and respectively obtaining data of influences of different flow velocity changes on the pyroxene glass-ceramic solidified body; data of influences of different pressure changes on the pyroxene microcrystalline glass solidified body and data of influences of different environment temperature changes on the pyroxene microcrystalline glass solidified body; and performing cross comparison analysis on the data of the influence of the multiple physical fields on the pyroxene microcrystalline glass solidified body, and evaluating the chemical stability of the pyroxene microcrystalline glass solidified body under the multi-field coupling action. According to the method, the deep geological treatment working condition
