The Research And Application Of Cement Soil Mixing Pile Strength Influence Factors And Change Regulation

In recent years, with the rapid development of China’s economic construction, the scale of infrastructure construction is increasing, but because of the low bearing capacity and low bearing capacity, it is necessary to deal with the soft soil. Therefore, the cement soil mixing method is used to deal with the soft soil foundation, and the cement soil mixing method is more and more important. Guide the influencing laws and lack of research in the marine strata in silt and silty soil is applied more and more widely. Therefore, the cement soil mixing pile research becomes more and more important, especially on the cement soil mixing pile strength influence factors, the domestic many scholars of the research, but the research on various factors influencing the system research, and the lack of regularity of the cement soil mixing pile strength influence factors and change rules of application, find out the factors of pile shaft strength. The influence law, whether the water soil mixing pile design theory, and the cement soil mixing pile engineering design and construction are Have important theoretical significance and engineering application value.The current domestic and foreign cement soil mixing pile technology and strength influence factors of do detailed induction and summary, at the same time of cement soil mixing the variation of pile shaft strength influence factors are analyzed in theory, and according to the characteristics of Zhanjiang Marine Strata in the muck and mucky soil, Zhanjiang steel project of cement soil mixing pile project as the research object, through a large number of laboratory tests and field tests, it is concluded that the incorporation ratio, curing age and water rate of cement soil mixing pile strength were investigated, and quantitative of cement soil mixing pile uniformity was determined. According to the results of the analysis are summarized, the effect of cement soil mixing pile uniformity Determinants of cement and soil mixing uniformity, send the uniformity of the slurry, continuous and stirring method used, the realization of the comprehensive utilization of various quantitative evaluation of factors judgment for the cement soil mixing pile body uniform decision provides a scientific method. At the same time for the cement soil stirring pile design and construction provides an important theoretical basis and practical foundation.
