The correct answer is: B. Draining the soil
The bearing capacity of a soil is its ability to support a load without collapsing. The bearing capacity of a waterlogged soil is reduced because the water fills the voids in the soil, reducing the soil’s ability to carry a load.
Draining the soil removes the water from the voids, increasing the soil’s ability to carry a load. This can be done by installing drainage pipes or by creating a trench around the foundation of the structure.
The other options are incorrect because they do not directly address the issue of waterlogged soil.
- Compacting the soil will not improve the bearing capacity of a waterlogged soil because the water will prevent the soil particles from being compacted together.
- Increasing the depth of the foundation will not improve the bearing capacity of a waterlogged soil because the water will still be present in the soil below the foundation.
- Grouting is a process of injecting a cementitious grout into the soil to improve its strength. This may be effective in improving the bearing capacity of a waterlogged soil, but it is a more expensive and time-consuming option than drainage.
