Curve setting pptNaufil Sayyad
油
Curves are used in transportation routes to gradually change direction between straight segments. There are several types of curves including simple, compound, reverse, and transition curves. A simple circular curve connects two tangents with a single arc, and is defined by its radius or degree. Transition curves provide a gradual transition between tangents and circular curves to avoid abrupt changes in grade or superelevation that could cause vehicles to overturn. There are several methods for laying out circular curves, including using offset distances from the long chord between tangent points or measuring deflection angles from the initial tangent.Theodolite survey

The theodolite is an instrument used to measure horizontal and vertical angles that is more precise than a magnetic compass. It can measure angles to an accuracy of 10-20 seconds whereas a compass is only accurate to 30 minutes. The theodolite is used to measure horizontal and vertical angles when objects are at a distance or elevation where more precise measurements are needed. The method of surveying that uses a theodolite to measure angles is called theodolite surveying. The theodolite can be used to measure angles, bearings, distances, elevations, set out curves, and for mapping and construction applications.Advanced surveying equipment ppt

Tacheometric surveying uses a tacheometer to determine horizontal and vertical distances through angular measurements. A tacheometer is a theodolite fitted with stadia hairs and an anallatic lens. The tacheometric formula relates the staff intercept, focal length, stadia interval and additive constant to calculate horizontal distances. Methods include stadia, fixed/movable hair, and non-stadia techniques. Determining the tacheometer constant involves measuring distances and staff intervals at stations to solve equations. Errors arise from incorrect stadia intervals or graduations. Tacheometric surveying provides distances in rough terrain but with less precision than other methods.Theodolite ppt in 7

Tacheometric surveying is a method that determines horizontal and vertical distances optically rather than using a tape or chain. It uses a theodolite fitted with a stadia diaphragm containing hairs to rapidly measure distances. There are different systems, including the stadia system which uses fixed or movable hairs, and the tangential system. Formulas are used to calculate distances and elevations based on staff intercept readings and vertical angles observed. The constants of the instrument such as the multiplying constant and additive constant must also be determined.Traversing Practical part 1

Abstract This research paper with how to facilitate and manage surveying instrument theodolite and total satiation and take more accuracy for civil works methods to accomplish modernized and cost effective urban survey with best achievable accuracy. This is done by surveying methods with modern methods from both theoretical and practical point of view. At first, a theoretical assessment process on a tradition urban planning project in India is performed by replacing other instrument of surveying techniques previously used with more applicable surveying techniques as theodolite and total stations, regarding different matters such as applicability, cost and accuracy. After approving the main idea of this modernization process, a practical urban planning case study is performed using total station, geodetic GPS receivers and GPS navigators, on a private sectors The applied surveying techniques showed high efficiency regarding cost and effort, while saving observation time reaching to 80%. Accordingly, the adopted practical application proved to be beneficial for all civil sites. Theodolite .ppt

This PowerPoint presentation provides a comprehensive overview of the Indian Soil Classification System, widely used in geotechnical engineering for identifying and categorizing soils based on their properties. It covers essential aspects such as particle size distribution, sieve analysis, and Atterberg consistency limits, which play a crucial role in determining soil behavior for construction and foundation design. The presentation explains the classification of soil based on particle size, including gravel, sand, silt, and clay, and details the sieve analysis experiment used to determine grain size distribution. Additionally, it explores the Atterberg consistency limits, such as the liquid limit, plastic limit, and shrinkage limit, along with a plasticity chart to assess soil plasticity and its impact on engineering applications. Furthermore, it discusses the Indian Standard Soil Classification (IS 1498:1970) and its significance in construction, along with a comparison to the Unified Soil Classification System (USCS). With detailed explanations, graphs, charts, and practical applications, this presentation serves as a valuable resource for students, civil engineers, and researchers in the field of geotechnical engineering.

- 16. Technical terms Swinging It indicates turning the telescope in the horizontal plane. It is called Right swing when telescope is turned clockwise and left swing when telescope is turned anticlockwise.
- 17. Technical terms Transiting The method of turning the telescope about its horizontal axis in a vertical plane through 180属 is termed as transiting. In other words transiting results in change in face.
- 18. Technical terms Face left Face left means the vertical circle of the theodolite is on the left of observer at the time of taking readings. The observation taken in the face left position is called as face left observation
- 19. Technical terms Face Right Face right means the vertical circle of the theodolite is on the right of observer at the time of taking readings. The observation taken in the face right position is called as face right observation.
- 20. Technical terms Changing face The operation of bringing the vertical circle from one side of the observer to other is called as Changing face.
