In situ tests give a more realistic picture of soil properties basically because of two reasons: i. The in situ tests cover a larger area and volume of soil mass than the laboratory tests which are conducted on small-size samples of soil. ii. Several site factors, such as non-homogeneity of soil, groundwater table, moisture content, cracks, fissures existing in the [...]
In this article we will discuss about:- 1. Introduction to Soil Exploration 2. Need for Soil Exploration 3. Planning and Execution. Introduction to Soil Exploration: Soil contrasts other civil engineering materials, such as steel, cement or concrete, brick, aggregate, or bitumen. All these materials can be manufactured with designated quality, for example, Fe500 steel, first-class bricks, 53-grade cement, 20 mm [...]
The following are the various methods used in soil exploration: 1. Test Pits or Trial Pits (for Shallow Depths) 2. Auger Boring (for Shallow or Large Depths). 3. Wash Boring. 4. Percussion Drilling. 5. Rotary Boring. Method # 1. Tests Pits: Trial pits are a simple and economical method of soil exploration to shallow depths. In this method of exploration, [...]
