http://www.aboutcivil.org/answers/3750/stability-of-railway-embankment
In the case of undrained shear strength analyze with a new embankment, do I need to consider the parameters of "undrained shear strength increase with ground level" and "the strength increase under embakment" ?<br />
<br />
How about in the case of an old embankment, with both using undrained shear strength and effective stress parameters?<br />
<br />

http://www.aboutcivil.org/answers/548/holes-determine-characteristic-required-150mw-power-plant?show=2675#a2675
The number of bore holes required for any hydro power project depend upon the geology and natural topography of the area. for example near the intake at least 3 or 4 bore holes are required up to the specified depth.<br />
<br />
However if the geology of the area is varying allot then more number of bore holes will be required to investigate the soil properties.Foundation Engineeringhttp://www.aboutcivil.org/answers/548/holes-determine-characteristic-required-150mw-power-plant?show=2675#a2675Mon, 07 Sep 2015 04:40:18 +0000Answered: Which type of foundation are commonly used?

http://www.aboutcivil.org/answers/338/what-type-of-footing-is-more-durable-and-economical?show=2444#a2444
<p>The type of Footing that is economical and durable depends upon the conditions where it is to be built. <strong>Like</strong> if a footing is to be constructed in an are where soil is too <strong>loose</strong>, so piles foundation may be more durable but not that economical. Similarly, if in the same conditions even piles <strong>cannot</strong> be installed due to hard strata being far below the reach than <strong>Matt footing </strong>will be durable but not economical.</p><p>So for a footing to be durable and economical, you have to find out the <strong>conditions of site</strong>, the <strong>options</strong> and<strong> alternatives available</strong> and then you have to choose the most durable and economical from the available options.</p><p><a rel="nofollow" href="http://www.aboutcivil.com/geo-technical-foundation-engineering.html">GeoTechnical & Foundation Engineering</a></p>Foundation Engineeringhttp://www.aboutcivil.org/answers/338/what-type-of-footing-is-more-durable-and-economical?show=2444#a2444Tue, 01 Sep 2015 05:56:03 +0000Answered: What is the purpose of shear force and bending moment diagram?

http://www.aboutcivil.org/answers/332/how-to-design-matt-foundation?show=2436#a2436
<p>How to Design Matt Foundation: Answer<br>There are many methods out there for the design of matt or raft foundation.</p><ol><li>First of all you should have idea or an assessment of how much thicknesses and other dimensions are required.</li><li>Designers usually rely on strip method i.e. take a strip of unit width along the length of the mat and analyze it as a combined footing.</li><li>This method is not very accurate and uses many approximation. But this will give you good idea for initial estimation say for further analysis, quick check and cost estimation purposes.</li><li>Finite element method may be best for detailed analysis because of readily available software for exact designs. There are some other methods also available e.g. ACI committee 336 proposed approximate flexible method, Finite difference method and finite grid method.</li></ol><p>Optimum design of mat foundation thickness based on type of soil, maximum allowable settlement, differential settlement, soil bearing capacity and recommendation of American Concrete Institute "ACI" can be obtained by using developed curves and charts.<br>Softwares that may be used to Design Matt Foundation are:</p><ol><li>ADAPT-MAT Foundation Design Software</li><li>Structure Point Matt Software</li><li>RISA Foundation design Software</li></ol><p>For more info:<br><a rel="nofollow" href="http://www.aboutcivil.com/geo-technical-foundation-engineering.html">Geotechnical & Foundation Engineering</a> | <a rel="nofollow" href="http://www.aboutcivil.com/soil-mechanics.html">Soil Mechanics</a> | <a rel="nofollow" href="http://www.aboutcivil.com/geotechnical-foundation-engineering-books.html">Geotechnical Books</a></p><p> </p>Foundation Engineeringhttp://www.aboutcivil.org/answers/332/how-to-design-matt-foundation?show=2436#a2436Tue, 01 Sep 2015 04:45:03 +0000Answered: What is the difference between soil nailing and reinforced earth?

Method of performing soil nailing?
http://www.aboutcivil.org/answers/201/how-to-do-soil-nailing-method-of-performing-soil-nailing?show=2340#a2340
A mass of reinforced soil is gradually built up while working from the top to downward. In order to keep the soil from caving in between the bars, some sort of facing needs to be installed. This is generally made with some shotcrete reinforced by a welded wire mesh. This facing can be vertical, battered to a wide variety of angles, or made up of a series of benches.<br />
The passive bars are often referred to as "nails" and the soil reinforcing technique is known as "soil nailing."Foundation Engineeringhttp://www.aboutcivil.org/answers/201/how-to-do-soil-nailing-method-of-performing-soil-nailing?show=2340#a2340Wed, 26 Aug 2015 09:08:47 +0000can you explain the newmark's chart for stress distribution?

We have 3 water detention ponds in our residential area.<br />
Some type of Willow trees have been allowed to grow on the water side of the dam near the exit pipes. They are not huge, but they are no longer saplings.<br />
I understand no trees should be on the dam. Do we cut them to the ground and risk their decaying roots creating a void in the dam, or do we leave them?<br />
What would be the best management practice?Foundation Engineeringhttp://www.aboutcivil.org/answers/452/we-have-3-water-detention-ponds-in-our-residential-areaThu, 02 Jul 2015 04:25:19 +0000what are the factors effecting the selection of foundation

A clay layer 6 m thick has the initial void ratio of 1.6 and effective ouverburden pressure of 125 kN/m2. When the sample is subjected to an increment of pressure of 125 kN/m2, the void ratio decreases to 1.4.
