Phương pháp tính toán sức chịu tải ngang của cọc đơn vùng đồng bằng sông Cửu Long khi gia cố lớp bề mặt móng cọc bằng xi măng đất

Abstract

In recent days, the theory to caculate the horizontal load capacity of single pile which has been popular for the types of pile with characteristic soil in construction. The use of Jet - grounting for reinforcing surface layer pile foundation is a relatively new solution in Vietnam. It is increased the horizontal load of works, especially the hydraulic works which the horizontal force is large. Selecting the appropriate calculation method as well as caculating the modulus of subgrade reaction (Ks) of the reinforcement layer which is supported to calculate the foundation design is favorable and effective. In this article, Author is concentrated to analyse caculating methods of the horizontal load capacity. After that, select to the caculating methods which is suitable for  Mekong Delta region. Beside, suggesting modulus of subgrade reaction (Ks) to representative soil in this region, soil layer is reinforced soil-cement, and how to caculate the the horizontal load capacity for popular piles.
