composite pile การใช้

• Research on load transfer law of cement - soil composite pile
• Reflections on design of composite pile foundations in nanjin district
• Study on partial factors of bearing capacity for composite pile foundation
• Research on reliability of the composite pile foundation settlement calculation
• Method of optimization design and practical engineering checking of composite pile foundation
• Steel composite pile
• Optimal design and applied example of composite pile foundation based on settlement control method
• Safety factor of composite pile foundation designed based on ultimate bearing capacity of single pile
• Reliability analysis of design method of composite pile foundation according to ultimate bearing capacity of single pile
• Composite foundation of composite piles is emphasized and widely accepted by all over the country because of its security and economical efficiency
• Optimum design model about composite foundation of composite piles is constructed which is under the dual control of bearing capacity and displacement by applying optimization theory
• For the sake of insuring the safety and as far as possible developing a mechanics function for pile - soil system , we can use rigid - soften composite piles foundation to handle the soft soil
• This paper investigates the piling characteristics of composite piles , studies the difference of piling engineering between composite piles and uniform piles , and puts forward the mode of composition of composite piles
• The distance between routine piles foundation is oversized in order to use soil ' s supporting capacity and think over the pile - soil ' s combined supporting capacity . this pile foundation is called composite pile foundation
• The purpose of this project is to probe the working character of non - linear interaction of pile - soil - raft considering consolidation and develop the theory of dual control of composite pile foundation
• Displacement and optimum design about composite foundation of composite piles are studied , which consists of broken stone pile and cfg pile . through analyzing field static test curve , the curve is sectional feature and the ratio of permanent deformation to total deformation is big
• Displacement formula for composite foundation of composite piles is derived by considering the coaction of foundation soil , broken stone pile , cfg pile and bedding cushion and by applying the theory of elastic - plastic mechanics , which is proper for superstructure being constructed
• Firstly , on the base of analysis and summarize already existing every kind of means to calculate the settlement of the foundation , and combinating stress peculiarity of the rigid pile in rigid - soften composite piles foundation , lodge a new method named utmost stress to calculate the settlement of it . it was proved useful with the practical example . besides that , bring forward a criterion that the calculation of the settlement must be bigger than the observation of it for 30 % to discriminate a method between safe and unsafe
• Based on my investigation and actual settlement measurement of pile foundation done by the testing center of jiangsu province on site , i made a conclusion : the strength and deformation of the original design could satisfy the standard requirement with composite pile foundation theory , and strengthening was not required
• Secondly , by using the great fem programme , analyzes the mechanism of bearing and deformation of rigid - soften composite piles foundation . draw a conclusion : exist a specific value , when the number of the rigid pile less than it , increase the number of the rigid pile , effect of reducing the settlement of rigid - soften composite piles foundation is distinct , on the contrary , when the number of the rigid pile more than it , increase the number of the rigid pile , effect of reducing the settlement of rigid - soften composite piles foundation is indistinct . finally , analyze and sum up some important design ' s constitutes of the rigid - soften composite piles foundation
