Transcribed Image Text:**Problem 7:** The clay stratum shown in the profile below has a total vertical stress of 200 kN/m² at its mid-height with a voids ratio of 0.98. When the vertical stress increases to 500 kN/m², the voids ratio decreases to 0.81. Find (a) the effective overburden pressure at mid-height of the compressible clay layer, and (b) the voids ratio of the clay if the total pressure at its mid-height is 1000 kN/m². **Diagram Explanation:** The diagram consists of a vertical section showing three layers: 1. **Top Layer:** - Material: Sand and Gravel - Unit Weight: 132 lb/ft³ - Elevation: Ranges from 760 ft to 752 ft. 2. **Middle Layer:** - Identified as the location of the Ground Water Table - Material: Sand and Gravel - Unit Weight: 132 lb/ft³ - Elevation: Ranges from 752 ft to 732 ft. 3. **Bottom Layer:** - Material: Clay - Unit Weight: 125.4 lb/ft³ - Elevation: Ranges from 732 ft to 710 ft, with a specific reference point at 721 ft. These layers illustrate the subsurface profile relevant to the problem, indicating the distribution of material and the potential influence of groundwater on stress distribution within the soil strata.

The diagram presents a cross-sectional view of geological layers and includes elevation markers, material descriptions, and unit weights.

- **Layer 1: Sand and Gravel**
- **Elevation**: 760 ft to 752 ft
- **Unit Weight**: 132 lb/ft³

- **Ground Water Table**
- Located at an elevation of 752 ft, indicated by a horizontal dashed line and an arrow pointing into the earth.

- **Layer 2: Sand and Gravel**
- **Elevation**: 752 ft to 732 ft
- **Unit Weight**: 132 lb/ft³

- **Layer 3: Clay**
- **Elevation**: 732 ft to 710 ft
- **Unit Weight**: 125.4 lb/ft³

- **Specific Elevation Point**
- Marked at 721 ft within the clay layer, represented by a dot.

These layers depict the stratification within the Earth's surface, highlighting changes in material and unit weight. The groundwater table is a significant feature affecting the properties and behavior of the materials above and below it.
