CTS-Z型重锤式料位计的改进

Improvement of CTS-Z Heavy Hammer Material Location Counting

在重锤锤击下，PDA得到一实测力信号和一实测速度信号，分析这些信号，可以得到桩承载力、桩身完整性和桩长、桩侧摩阻力分布和桩身应力。

By analysing measured force and velocity signals under the impact of a heavy hammer the bearing capacity , degree of integrity and inner stresses of a pile , as well as the soil resistance distribution along its length can be given by the PDA .

地面重锤横向敲击枕木激发的水平分量的SH型横波数据信噪比较高，其垂直分量纵波初至的信噪比不高；

The S / N ratio in SH-wave data of horizontal components shooting by hammer on the surface hammering at sleeper laterally is higher , but S / N ratio of the first breaks of P-wave in vertical components is not high ;

试验结果表明，排水固结过程中填土层的单位沉降量远小于淤泥质软土，重锤夯实法的有效加固深度可以达到地表下3.5m，影响深度可达6.0m。

The strengths of fill and soft clay were increased . The results of test show that the unit settlement of saturated soft clay is much more than that of fill soil in process of drainage consolidation ; the effective consolidation depth of tamping method is 3.5m ;

由于楼层高、工期紧，为确保主体结构工程质量，垂直度控制采用激光&重锤双控轴线引伸技术，使用JD-91型建设激光测量仪。

Due to its huge height , its urgent time schedule and strict requirement of fine quality , its construction has been duly guided and controlled by application of the JD-91 type laser-heavy plumb bob surveying apparatus with a double controlled axial line extended technology .
