Question

**Consider the MSE Retaining Wall:**

Assuming that the reinforcement is a geotextile fabric with \( T_{\text{ULT}} = 10500 \) lbs/ft. **Only consider internal stability.** Do not check external stability. Assume that the backfill material and the native foundation soil have nearly identical soil properties: \( \phi = 31^\circ \) and \( \gamma = 130 \) pcf. **Evaluate the wall at 2 ft, 10 ft, and 20 ft below the retained ground surface.** Determine the most appropriate vertical spacing (\( S_v \)) and total length of the reinforcement needed for the wall considering the requirements at each depth.

\( H_1 = 22 \) ft and \( H_2 = 3 \) ft.

---

**Diagram Explanation:**

The diagram illustrates a cross-section of an MSE retaining wall, represented as a vertical structure supported by horizontal reinforcements. The diagram consists of:

- **Vertical wall segment:** This represents the height of the retaining wall.
- **Horizontal lines:** These represent the reinforcement layers extending horizontally from the wall.
- **Dimensions:**
- \( H_1 = 22 \) ft, the height of the main retaining wall.
- \( H_2 = 3 \) ft, the depth of the footing below the ground surface.

The task involves evaluating the structure at specific depths—2 ft, 10 ft, and 20 ft below the ground—to assess necessary reinforcement spacing and length.
