Scenic Lake Dam Phase 1 Deep Mixing Method Stabilization John James Audubon State Park

The following list below was Raito's proposed structured plan.

1. Mobilize Cone Penetration Testing (CPT) rig.

   1. Essentially continuous data on soil strength correlations (every 5 cm)

   2. Obtain seismic shear wave velocity of material

2. Deterministic Seismic Hazard Analysis (DSHA)

   1. Determine rock accelerations for Maximum Credible Earthquake (MCE) M=6.8

3.  Run QUAD4M analysis

   1. Utilizes Shear Wave Velocity data from CPT

   2. Determine seismic stresses (CSR values) for actual cross section and material geometry

4.  Revise Liquefaction Analysis with high quality site-specific data

   1. Accurately determine susceptibility to liquefaction

   2. Determine residual or “liquefied” strengths of soils

5.  Run post-liquefaction stability analyses based on previous models
