CFG桩的面积置换率怎么算

Zhengzhou region of saturated silt in the long spiral occurs when the CFG pile liquefaction,soil strength decreased.The soil above the groundwater level is not saturated,liquefaction does not occur,that the soil strength in the spiral leaves little perturbed reduced.In order to simulate the displacement of groundwater level on the impact of drilling in the vicinity,located in the soil above the groundwater level in the construction of intensity is not reduced below the water table in soil disturbance by construction,the intensity decreases.The soil above the groundwater level in the material used in Table 1 Ⅰ strength parameters,the groundwater level below soil parameters using materials Ⅷ.When the drilling depth is 15m when the deformation of different water table on the drilling results shown in Figure 8,the same as drilling depth,ground load change,the crack center point position of F from the drilling location are 3.2m.

最大压力440KPa,换算吨位要乘以压板面积再除以10,至于千斤顶读书,和千斤顶的标定值有关!

低应变检测是通过声波在混凝土中的传播速度和传播时间检测桩身混凝土的完整性（也就是通常说的断桩检测）、桩长.检测率就是指的接受低应变检测的桩数占本工程全部桩数的比值.
