一切基桩工程,在施工前,必须先打试桩,较重要的工程,除进行动载重试验外,还必须进行静载重试验,包括垂直及水平载重试验,因为它具有下列重要意义:1)能求得最经济的桩长及桩的构造种类型式;2)能选择最有效的打桩机械与配用零件;3)对打桩的工程费可以作到比较准确的估计;4)能求得准确的土壤弹性抗力系数k及土壤的单位承压力σ_Ο以便参考;5)能求得桩的垂直与水平极限荷载。为此,作者特根据过去在工地的经验,把工地静载重试桩的简易方法介绍如下: All foundation piles, before construction, must first test piles, more important projects, in addition to the dynamic load test, static load test must also be carried out, including vertical and horizontal load test, because it has the following significance: 1) 2) Can choose the most effective piling machinery and matching parts; 3) Can make a more accurate estimate of the construction cost of piling; 4) Can get the accurate Soil elastic resistance coefficient k and soil unit bearing pressure σ_Ο for reference. 5) The vertical and horizontal ultimate loads can be obtained. To this end, the author based on past experience in the field, the site of static load test reposted simple method described below:
