Among the following, which doesn't belong to tunnel classification?

Which of the following should be considered while aligning a tunnel?

In 'building integrated photovoltaic glazing', buildings are provided with

India's first ZNE building is

Length of (SARDAR SAROVAR) main concrete gravity dam

The elongation of a conical bar under its own weight is equal to

A prismatic beam of length 1 and fixed at both ends carries a uniformly distributed load. The distance of points of contraflexure from either end is

A long column has maximum crippling load when its

The ratio of maximum shear stress deve- loped in a solid shaft of diameter D and a hollow shaft of external diameter D and internal diameter d for the same torque is given by

Rise of water table in cohesionless soils upto ground surface reduces the net ultimate bearing capacity approximately by

The unit weight of a soil at zero air voids depends on:

Given below are methods of compaction:

1. Vibration technique 2. Flooding the soil 3. Sheep-foot roller 4. Tandem roller 5. Heavy weights dropped from a height The methods suitable for cohesionless soils include

The moment required to rotate the near end of a prismatic beam through a unit angle without translation, the far end being simply supported, is given by

For a two-hinged arch, if one of the supports settles down vertically, then the horizontal thrust

Find correct for
Sinking of an intermediate support of a continuous beam 1.reduces the negative moment at support.
2.increases the negative moment at support.3.reduces the positive moment at support. 4.increases the positive moment at the centre of span.

By approximate method, the computation of N component at the time of sudden drawdow condition, the weight is considered as:-

The ratio of a given volume change in a soil, expressed as percentage of the dry volume, to the corresponding change in water content is called

A soil has the liquid limit of 60 % and plastic limit of 20% Then the classification of soil a per IS soil classification system is
