| 摘 要： | 基于复合地基和刚性桩基的受力机理、桩的定位精度分析,认为规范中对水泥土搅拌桩地基的桩偏位规定过于苛刻,参照混凝土灌注桩及其他复合地基桩偏位规定,提出对水泥土搅拌桩偏位作适当修正.理论分析和实践表明：适当放宽桩偏位标准是合理、可行的,而且更符合水泥土搅拌桩地基作为复合地基的特性.

| Abstract: | Based on the stress mechanism with composite foundation and rigid foundation, and the accuracy grade of pile positioning, the author believes that the existing technical standards for pile displacement in soil-cement mixed pile foundation are unreasonably rigorous. Proper modifications to the existing displacement standard for the soil-cement mixed pile are proposed with reference to specifications for cast-in-place concrete pile and other composite foundation piles. Theoretical analysis and practice both indicates that a more tolerant standard for pile displacement would be reasonable and feasible, and better meet the characteristics of soil-cement mixed pile foundation as a composite foundation. |
