Dynamic Response Analysis of Buried Drainage Pipes for Polymer Grouting Trenchless Rehabilitation under the Traveling Wave Effect

Figure 12

Time course curves of transverse vibration displacement of pipes under normal, vacant, and polymer grouting repair. (a) At 800 m, wave speed  = 100 m/s. (b) At 500 m, wave speed  = 200 m/s. (c) At 200 m, wave speed  = 500 m/s.
