| 摘 要： | 同一地区、工程地质条件近似、桩径相同情况下,灌注压浆桩比普通灌注桩可缩短桩长1/3,而承载力提高1/3,沉降量减小1/3,还降低工程造价,是值得推广的一种桩型。

| Abstract: | Under the conditions of similar engineering geology and same pile diameter in the same area,the length of pressure grouting pile is 1/3 shorter than that of common grouting pile,the bearing capacity of the former is 1/3 higher than that of the latter and the sinking value of the former is 1/3 less than that of the latter.And the former one can also decrease the cost of engineering.Therefore,it is worth popularizing. |
