Triangulation Method of Surveying in Civil Engineering

 


Triangulation is a surveying procedure that helps to estimate the angles in the triangle, which has been formed by the three survey control points. A network of triangles has been traced and measured by the triangulation surveying method, which helps to determine the distance and the points’ positions across the area.

In the case of hilly terrain, the conduct of the triangulation surveying procedure is advantageous. In the triangulation surveying process, the entire area has been covered along with a network of triangles, and the surveying process has been started with a precisely measured baseline. The triangulation surveying procedure extends and interconnects the triangles, which helps to form a comprehensive framework throughout the entire surveyed area.

Reasons behind conducting the Triangulation Survey Procedure

The triangulation survey procedure helps to establish an accurate control network, which acts as the backbone of engineering projects. The main reasons behind the conduct of the triangulation method of surveying are:

➢ The triangulation survey procedure helps to set more accurate control points for the geodetic and plane surveys with the help of its ground-based techniques. These types of control points are crucial to ensure the accuracy throughout the entire surveying method.
➢ The critical ground-based control points have been provided by the triangulation method of surveying in the case of photogrammetry.
➢ The triangulation method of surveying also helps to get precise locations to conduct the large-scale engineering works. The determination of the accurate location is crucial to fix the centerline and terminal points for the long tunnels, position the centerline for the bridges, observe the movement of the cloud and transfer the control points throughout the wide sea channels.
➢ Several modern technologies, including satellite-based systems and GPS, help to improve the effectiveness and accuracy of the triangulation survey procedure, which helps to achieve more precision throughout large areas.

Benefits of conducting the Triangulation Survey Procedure

There are several benefits of conducting the triangulation survey procedure, which are as follows:

Bridge Types: An Explanatory Guide with Different Types

Image
  Developing bridges that are unique and safe for people begins with an understanding of bridges as a construction worker and civil engineer. For a bridge to carry a lot of vehicles year after year & decade after decade, you must calculate its daily vehicle load. Arch Bridges A classic bridge type, arch bridges are the oldest bridges after girder bridges in terms of architecture. Stone is well suited to arches as opposed to simple girder bridges. A typical arch does not require piers in the center, making it an attractive choice for crossing valleys and rivers. There are many types of bridges, but arch bridges can be one of the most beautiful. Arches are built with curved structures that are highly resistant to bending. As opposed to girder and truss bridges, arch bridges are fixed horizontally on both ends, so they can only be used on solid ground. The arch bearings experience horizontal forces when a load is placed on the bridge. There are some cases in which the roadway pass...
