Proceedings of the Eighth Regional Conference for Africa on Soil Mechanics and Foundation Engineering /Harare / Geotechnical evaluations for tailings. The application of the principles of soil mechanics to the design and construction of foundations for various structures is known as ''Foundation Engineering''. The basic aim of Soil Mechanics and Foundation Engineering written by Dr.K.R. Arora is to present the fundamentals of the subject in a simplified manner.

What are the effects of water on the unit weight of soils?

Soil Mechanics & Foundation Engineering P. Purushothama Raj

What factors affect the compaction of soils? Physical weathering involves reduction of size without any change in the original composition of the parent rock. The main agents responsible for this process are 2.

Chemical weathering causes both reductions in size and chemical alteration of the original parent rock. The main agents responsible for chemical weathering are hydration, carbonation, and oxidation. Often, chemical and physical weathering take place in concert. These soils retain many of the elements that comprise the parent r ck.

Alluvial soils, also called fluvial soils, are soils that were transported by river and strea s. The composition of these soils depends on the environmen del' hich t ey were transported and is often different from the parent r k. Muc our ities has been and is occurring in and on alluvial soils.

About this Journal. Continue reading On one hand, Terzaghi defined creep as the continuous deformation under constant effective stress, and plenty of studies on creep behavior of various soils by oedometer test have been based on this definition 2 , 3 , 4 ; on the other hand, other researchers 5 , 6 , 7 , 8 , 9 , 10 , 11 proposed creep could be taken into consideration in the whole consolidation process, as the mechanism 12 governing the creep behavior should not change between primary consolidation and secondary compression.

The latter statement is further supported by creep research on sands by oedometer test 13 , 14 , 15 , The assumption of constant stress is the crucial condition.

The study of creep behavior is often conducted under constant total stress in various fields of science and engineering. The initial definition of creep, however, in materials science, is particles and the structure of a solid material slowly adjusting to resist the applied external stress in the long term. This definition has never explicitly and implicitly stated that creep should be under constant stress.

In this article, creep is considered as a time dependent deformation, regardless whether the applied stress is constant or not.

Design Aids in Soil Mechanics and Foundation Engineering by Kaniraj.pdf

Lab test performed by Casagrande and Wilson 17 in Massachusetts Institute of Technology MIT on clays and shales, first studied creep as rate of loading. They found that the ultimate strength is significantly lower than results of tests with slower rate of loading: the slower the rate of loading, the lower of the ultimate strength obtained.

Three routes are introduced in Fig. Under Route 1 with a fast rate of loading 1 minute , a soil loads from point A to reach point B, then creeps 1 week to reach point C, and then continues to creep slightly less than years to reach point D.

Under Route 2 with a quite slow rate of loading 1 week , a soil loads from point A to reach point C, and then continues to creep slightly less than years to reach point D.
