Abstract-Piles are built to transfer the load of superstructure to the deeper more durable soil strata crossing the higher weaker strata of soil. Cast in situ piles are usually intended by a lot of analyses and making use of a lot of empirical formulas. But as a result of an excellent diploma of prevailing uncertainties of subsoil habits, variation of strata in a similar website, variety while in the course of action of design used at web page, piles are required to be analyzed to double or so of design and style load to confirm the conformity with that structure load obtained by static design and style calculation. A scenario review of load take a look at on a pile of 600mm diameter & size of 35.250m was conducted by way of ASTM D 1143-81 strategy. The check load knowledge have been collected and transformed into graphical varieties. The outcome were interpreted by load-settlement curves applying several approaches for determining the allowable load bearing ability on the pile. Keywords and phrases: cast in situ piles, design and style load, load bearing capacity, static layout calculation, load settlement curve.
Website traffic congestion continues to be An important challenge in urban transportation organizing for big metropolitan areas Irrespective of numerous initiatives. 1 of these cities suffering from abnormal targeted traffic congestion is Dhaka, the funds of Bangladesh that has a populace of a lot more than 22.4 million. Any urban highway intersection's visitors movement has usually been an advanced, nonlinear method. Among the list of key contributors to ... [Demonstrate total summary] metropolitan site visitors congestion is the overuse of personal automobiles and rickshaws, yet neither their effects nor probable options have already been totally analyzed. This examine looked into the key complications with highway travel in Bangladesh, and much more precisely in Dhaka. The primary knowledge for your research was gathered within the websites and also other pertinent knowledge resources, by way of example, the street and transportation Site. Secondary information was gathered from journal content articles, the daily newspapers of Bangladesh and also other on-line sources.
Bored cast in situ pile is good as finish bearing pile, completely when it have to be socketed into rock.
Precast concrete is usually a more affordable constructing content if large constructions should be crafted. Even so, routine maintenance expenditures for precast concrete structures are bigger.
A pile foundation is taken into account for design Any time the load of the composition is significant, along with a thick and weak soil layer is existing below. This is a kind of deep Basis that transfers the load with the superstructure into a stiff layer with the weak soil strata.
Precast concrete piles have substantial resistance. Their principal reward is really a significant vertical pile load. The allowable capacities for concrete piles on the structure-Develop foundation range between 125 to more than 750 kips per pile.
Exactly where floor circumstances are really variable as they are pushed to a set or pre-identified resistance

Geologically Bangladesh is made up of young fluvio-deltaic deposits of Mio-Pleistocene age. Most of the landmass is inundated through monsoon. As a result of intricate river system and flooding, innumerable bridges and drainage buildings are integral element of your highways. Till seventies, bridges had been normally built on masonry caisson foundations. Presently rather than caissons bored cast-in-situ reinforced concrete pile is extensively adopted in bridge Basis mainly because it is uncovered cost-efficient, it saves considerable building time as well as machines and technology is readily available.
It calls for much less personnel to finish. On developing web pages, proficient workers are required. A educated and expert contractor is needed to build the precast concrete construction. Precast concrete involves significant equipment and cranes for dealing with, that is, lifting and setting up major aspects.
