A tunnel is an underground or underwater (or both) route for the transit of people and/or goods. The tunnel is surrounded by rock or other earthen materials, water or other things, and these all apply pressure on the structure of the tunnel. Sometimes these structures fail.
The failure of a tunnel can come as the result of poor engineering or construction. A "bad" design or the failure of the construction crews to follow a design can leave a tunnel vulnerable to failure. Additionally, there may be earthquakes or other natural disasters, fires or explosions in the tunnel, or other events that the tunnel was not made to withstand, and collapse is possible under the circumstances.

What are various design factors that influence energy saving in building construction?
I presume you mean that you want the completed building to save energy as opposed to the construction process. First and foremost is holding on to heat (or cold) that you're paying to create (you "pay" for firewood with your time, energy and the various costs associated with your chainsaw and splitting gear). Insulation and sealing inside against outside are the keys to this endeavor. Some of the most highly effective ways of pursuing these goals are "Earth Bermed/ Sod covered/ or Underground construction and the use of vestibules to prevent the wholesale loss of conditioned air when someone enters or leaves. Kind of like an "Air Lock" on a space shuttle (or an as-yet fictional Star Ship). For many folks, siting a house into a south facing slope is not practical. Other factors become more important (they're always important). There are limits to how much you should seal a house (especially in moist environments). Highly efficient appliances, though expensive, have usually paid for the cost difference somewhere from 3 to 10 times over the life of the appliance. In these days of greater energy costs, that number should be greater. Natural lighting can be a huge efficiency factor, as can be having properly calculated windows and overhangs on the East, South and West sides of your house. There are many good books on "Solarizing" your house plans. one I highly recommend (if you can find it is called "other Homes and Garbage" (a play on "Better Homes and Gardens" magazine title).
Why shear force and bending moment is zero in trusses?
An ideal truss has pin joint connections, allowing laod to be taken only in tension and not in bending or shear.
In reality, truss joints are not pinned, and do carry some moment and shear, but because tensile stiffness dominates, the moments and shears are small and called secondary.
What is the yearly average salary of civil engineers in South Africa?

In terms of volume and length it is the Great Wall of China (just over 5000 Km). In area, it is the low lying area of the Netherlands that have been reclaimed from the Sea (which means that the usable land is technically "man made"). By height, it is currently the Burj Dubai. In extension (length) it would be the internet.

Importance of anthropometrics?
Anthropometrics literally means man (anthro) measurements (metric). It is the measurement of the size and proportions of the human body, as well as parameters such as reach and visual range capabilities. Anthropometrics enables us to properly size items, including system interfaces, to the "fit" the user.

Who used the Bering land bridge?
It is not who, but what. The land bridge was created by a lowering of the sea level when huge amounts of water was stored in ice caps, or glaciers. When the ice age ended, all of the water that was trapped inside was released back into the sea, and the land bridge was consumed.
Who was the leader of the battle of Great Bridge?
(Since this is world wide please note:Americans use the term Tories where English use Loyalist to describe those loyal to the crown. Likewise they use Whigs where English use Patriots.) Lord Dunmore commanded the British Army. William Wofford commanded the Whig Army. On December 9, 1775, Lord Dunmore's army found the Whig army encamped behind large earthworks near The Great Dismal Swamp in Virginia at Great Bridge.
The British Army would climb the earthworks into a volley of gunfire. Then it would retreat. The British officers believed that eventually the Whigs would run out of ammunition like they did at Bunker Hill. Then they could overpower the Whig army with fixed bayonets. Before the Whigs ran out of Ammunition, a large Whig militia force from North Carolina joined the battle. The British were outnumbered and abandoned the battlefield. They fled to the Tory town of Norfolk, Virginia.
How do you think Rome's roads eventually helped lead to the downfall of the city?
First of all, the city of Rome never fell. It was sacked four times during antiquity (by the Senone Gauls in 390 BC, by the Visigoths in 410, by the Vandals ion 455 and by the Ostrogoths in 566). However, it was never conquered or destroyed. In fact the city still exists today. The Visigoths did not intend to seize Rome. They moved on to the south of Italy after the sack. The Vandal sack was an act of looting. The king of the Ostrogoths had wanted to destroy the city, but relented as he had been helped to enter the city by the Roman imperial garrison and left to pursue the Byzantine army in Apulia. The Byzantine general then retook the city.
What fell was the western part of the Roman Empire, which collapsed under the weight of the invasions by the Germanic peoples. One could say that the Roman roads made the penetration of this part of the empire by invaders easier. However, the roads in themselves did not prompt the invasions. Moreover, the Romans lost political cohesion. There were usurpations and a lot of infighting and the Romans failed to deal with the invasions adequately. Therefore, if the Roman roads did help the downfall of the western part of the empire, this would have been a very relative factor.
