The particle size distribution of the soil is shown in Fig. 5 , and the properties of
the residual soil are summarized in Table 3.

3 TEST PROCEDURES

A series of blasts was detonated at various locations around the RS and RE walls.
However, for discussion in this chapter detonation events MD5-E2, MD5-E3,
MD11-E2, and MD11-E3 were referred to for comparison of performance
