［摘要］闡述了勁性復(fù)合樁的受荷機(jī)理及承載特性，通過實測研究了勁性復(fù)合樁施工過程中的環(huán)境效應(yīng)，對施工過程中的孔隙水壓力、深層土體位移進(jìn)行了詳細(xì)的監(jiān)測和分析，研究證實了勁性復(fù)合樁施工時擠土效應(yīng)微弱，影響范圍有限，為進(jìn)一步工程應(yīng)用提供了詳實的依據(jù)。對比分析了勁性復(fù)合樁的碳排放量、工程造價與施工工藝，結(jié)果表明，勁性復(fù)合樁不僅具有良好的經(jīng)濟(jì)優(yōu)勢和施工效率，而且更為節(jié)能環(huán)保，具有廣闊的推廣價值。

Abstract:The loading mechanism and bearing characteristics of the stiff composite pile were expounded, and the environmental effect of the construction process of the stiff composite pile was studied through the actual measurement, and the pore water pressure and the deep soil displacement were monitored and analyzed in detail. The study proves that the effect of soil compaction is weak and the influence range is limited during the construction of stiff composite piles, which provides a detailed basis for further engineering application. The carbon emission, construction cost and construction technology of the stiff composite piles were compared and analyzed. The results show that the stiff composite pile not only has good economic advantages and construction efficiency, but also is more energy-saving and environmental protection, and has broad popularization value.
Keywords:stiff composite pile; pore water pressure; deep soil displacement; bearing capacity characteristic; environmental protection and energy saving
