What is the importance of soil exploration studies while selection of type of foundation?

What is the importance of soil exploration studies while selection of type of foundation?

Purpose of soil exploration is: (i) To determine the basic properties of soil which affect the design and safety of structure i.e., compressibility, strength and hydrological conditions. (ii) To determine the extent and properties of the material to be used for construction.

How do you design a foundation?

Design Procedures for a Building Foundation (Step by Step)

  1. Decide the Location of Columns & Foundation and Type of Loads Acting on Them.
  2. Estimate Allowable Bearing Pressure of Soil Using Ground Investigation Report.
  3. Decide Depth of Foundation.
  4. Calculate Foundation Area.
  5. Determine Variation in Vertical Stresses.

What are the factors to be considered while designing the foundation?

Factors to Consider in Foundation Design

  • Footing Depth and Spacing. The foundation shall be designed in such a way that the bottom of the foundation is located below the frost line.
  • Soil Settlement.
  • Soil Erosion.
  • Foundations in Sand and Silt.
  • Foundations in Loess and Other Collapsible Soils.

What type of foundation is suitable for soil?

Loam
Loam. When it comes to the ideal soil type for foundations, loam may be the best option. Generally, loam is a combination of clay, silt, and sand.

How do I choose a foundation for different soils?

Recommended foundation One of the following types of foundation may be selected: concrete piles supporting reinforced concrete ground beams and precast concrete floor. concrete piles carrying in situ concrete slab. specially designed trench fills in certain clay soil based on the foundation location relative to trees.

What are the objectives of soil exploration What are the steps involved in the planning and execution of soil exploration?

i. To determine the location and thickness of various soil and/or rock strata up to a significant depth. ii. To collect soil or rock samples at locations that represent changes in soil characteristics across the area and depth for conducting laboratory tests to determine the basic and engineering properties.

What is the soil exploration?

Soil Exploration • The process of collection soil data for the assessment soil properties at a site through series of laboratory and field investigation is collectively called Sub-soil Exploration • Enables the engineers to draw soil profile indicating the sequence of soil strata and the properties of soil involved. 3.

What is the foundation of a structure?

In engineering, a foundation is the element of a structure which connects it to the ground, transferring loads from the structure to the ground. Foundations are generally considered either shallow or deep.

What are the requirements of good foundation?

What are the Requirements of a Good Foundation?

  • Permanence. It’s essential for foundations (and the building itself) to be placed in an area in such a way that it will not be affected by future construction work or projects.
  • Stability and Cohesion.
  • Depth.
  • Consistency.

What points should be kept in mind while designing and constructing foundations in such soils?

Following factors need to be considered in design and analysis of foundations:

  • Footing depth and spacing.
  • Displaced soil effects.
  • Net versus gross soil pressure: design soil pressures.
  • Erosion problems for structures adjacent to flowing water.
  • Corrosion protection.
  • Water table fluctuation.

What is a foundation design?

Foundation design is a process of designing the footing and foundation walls of the structure. The footing can be of many varieties, for example, strip or continuous footings, drilled piles, mat foundations, etc. Designing a foundation is dependent on the geotechnical report.

How does soil exploration affect a building design?

The data obtained from soil exploration will have a significant bearing on the stability of the structure, choice of a safe and economical foundation and its design, as well as successful completion of construction of the structure on time.

Why do you need to test the soil for a foundation?

For most construction projects of any magnitude, it is highly desirable to investigate the compaction characteristics of the soil be means of a field test section. Suitability of soils for foundations depends primarily on the strength, cohesion and consolidation characteristic of the soils.

What do you need to know about soil engineering?

The safe and economical design of foundation of any structure, supported on soil, requires the knowledge of the physical and engineering properties of the soil up to a depth of 1.5-2 times the width of the foundation or structure below the base of the foundation.

What is the purpose of a soil exploration programme?

A detail soil exploration programme involves deep boring, field tests and laboratory tests for determina­tion of different properties of soils required for the design of any structure. (i) To determine the basic properties of soil which affect the design and safety of structure i.e., compressibility, strength and hydrological conditions.
