Sanya Hongsha Coast Foundation Design And Construction

The main contents in this article is to deal with the foundation of 8# floor of Hongshahaian District Sanya. Inside this text did the necessary description to environment, engineering geological condition and geotechnicil engineering condition of the construction area. The most important part of this article is the design calculation part. in this part,respectively made composite foundation and loading dint calculation respectively to the natural foundation,cement soil mixed blend composite foundation,Cement Flyash Gravel Pile composite foundation and concrete pipe pile. At first satisfied the engineering demand and later made a simple economy contrast to every kind of the handle.Pipe pile is a new pile type which development in the last few years. Because it have a lot of advantages, So it have the very extensive apply foreground. The main advantages of the pile foundation is:Low noise,no vibration and no pollution.have quick construction speed and can continue construction in 24 hours; At the same time,the ground is clean and neat and the civilization degree is high; Because of the sending machine fits together with the contact face of the engineering pile head very well, the sending machine in the process of senging piles can't vibration right and left and jump up and down, as a result it can send the pile deeper, the pile will be cut down little after openning dug; In construction process,pile shaft can't appear tensile stress, the head of the pile is general prefect,and reply to press is easily.Certainly, there is also not enough place,there is a simple introduction about it,now it as follows:the pile make the soil crowded andhave certain influence to the surroundings,requesting side pile center arriving close building is more longer; the request to the construction eara is higher,in made ground, silt soil and the area that water soaked construction district will make the machine sink easily; Is not suitable for construction in the area in which there is more abattis underground or lonestone; Over pile pressure ( clamping force) will make the pile breakage easily.
