shear and tensile capacities of PHC pile are the highest among these four types of concrete piles,the PRS pile takes second place,the PHC pile is the lowest.With the same area of longitudinal bar,tensile capacity and flexural capacity of PRS pile are 1.9 times and 1.7 times of that of ...
Pile foundation, a kind of deep foundation, is actually a slender column or long cylinder made of materials such as concrete or steel which are used to support the structure and transfer the load at desired depth either by end bearing or skin friction.
INTEGRITY TESTING OF CONCRETE PILES BY SHOCK METHOD Mention is made of the need of a comprehensive quality control test for all piles in a foundation, due to the increased use of cast-in-situ piles as oppose... JS Higgs 被引量: 18发表: 1979年 Propagation characteristics of transient waves...
aGiven two concrete types A and B (for example, Number and Integer), MyClass has no relationship to MyClass, regardless of whether or not A and B are related. 给出二个具体类型A和B (,例如数字和整数), MyClass没有关系对MyClass,不管是否A和B是相关的。[translate]...

Design Considerations of Piers for Bridges: ADVERTISEMENTS: The masonry or mass concrete piers arc designed with vertical loads and moments acting on the piers such that the resultant falls within or very near to the middle third line. By this limitation, it will be possible either to arrive at...
Introduction: Precast piles are piles of various materials and forms (such as wood piles, concrete square piles, prestressed concrete pipe piles, steel piles, etc.) made in factories or construction sites. They are pressed or vibrated into the soil. Concrete precast piles and steel piles are ...
one of their major disadvantages is the lack of quality control over the concrete poured into the shaft for the seal. Also，the bottom of the caisson cannot be thoroughly cleaned out. An alternative method of open-caisson construction is to drive some sheet piles to form an ...
and its tip rests on a strong load-bearing soil layer or rock. The shaft can be cased with steel shell or pipe when required ( as in the case of cased，cast-in-place concrete piles) . For such shafts，the resistance to the applied load may develop from end bearing and ...
an indirect approach can be used to work out the bearing capacity of multi-pile composite foundation. The so-called indirect approach is to carry out static load test of single pile or composite foundation separately for primary piles and secondary piles 除了上面被提及的静态的负荷测试的直接方法,...
