Influence of explosive enlargement and explosive lining on moisture content of soil

The test procedures of explosive enlargement and explosive lining in soil were introduced,and the measured data were presented and analyzed.It was shown that different zones were formed in the surrounding soil of explosive enlarged cavity and they were in turn zones of lowering,rising and restoring moisture content.The moisture content distribution formed by explosive lining was the superimposed effect of explosive enlargement and explosive lining,and different zones in the surrounding soil of explosively formed lining were the infiltration zone,and zones of lowering,rising and restoring moisture content.
