For the not yet completed the consolidation of the fill weight and the garbage-based fill, not counting the side resistance; 2.0-water ratio, 0 = w / WL; 3. According to soil (rock) layer depth, the correction factor qm by the following table: 123 Table 3 limits of static pile tip resistance standard value qpk/kPaTable3Thestandardvaluesofultimateendresistanceo fstaticallypressedprecastconcretepilesqc. / KPa sand gravel breccia, round gravel in the dense, dense, medium dense, dense 63oo-lO5oo7400-11800 gravel, pebbles in the dense, dense 8400-12700 granite clay 0.25 <IL <~ O. 7518oo a 26o026oo a 31oo31oo a 39003900-4500 residual soil, L ≤ 0.2526oo a 34oo3400-46004600-560056oo a 6400 (including all sandy clay 0.25 <, L ≤ 0.7519oo a 28oo28oo a 34003400-43004300-4700 weathering, L ≤ 0.252900 ~ 380038oo a 47004700-54005400-6700 rock) gravelly clay 0.25 <, L ≤ 0.7520oo ~ 3oo03000-370037oo a 48004800 ~ 5700, L ≤ 0.253200-4oo04000-49004900 ~ 59005900-7oo0 weathered rock Note: L is the pile embedment depth. According to equation (3) to estimate the static pile Pile bearing capacity at the same time, should be (4) estimate the static pile pressure on the final value. ≥ Qk (4) where, for the static pile pressure on the final correction factor, obtained by the statistical analysis (statistical analysis specifically omitted), see Table 1. At the same time according to indicators of soil mechanics spreadsheet, get all types of static pile ultimate lateral resistance of soil standard value q. ik tip resistance standards and limit values of q, respectively, Table 2 and Table 3. Static pile Pile bearing capacity design values can be used the following formula to determine R = Qk /. (5) where,. For the static pile side resistance, end resistance integrated resistance partial coefficient, take call-in = 1.65. 1244 Conclusion This article is in the preparation of static pile foundation design and construction experience data, the choice to present to you some findings, these results although there is no deep theory, but the design and construction is to meet the requirements. As background material and data is only part of the main areas of Guangdong, a summary of results of limited data, hoping to be accompanied by guidance to the static pile foundation design and construction technology to mature. The authors thank members of the group co-written rules of labor, not the details in this column.
