| 摘 要： | 通过模型试验与现场试验,论证了轻便触探检测桥涵台背中粗砂的相对密实度的可行性,并与静力触探进行了比较,验证了其合理性。在此基础上,通过简单统计建立了轻便触探锤击数N10与相对密实度Dr之间的经验关系,提出了用轻便触探检测公路桥涵台背回填中粗砂相对密实度的试验方法。

| Abstract: | On the basis of lab and field tests,the feasibility of light penetration is proved to test coarse sand relative density at abutment back of bridge-culvert back sand filling.And its reasonability is testified through comparison with static penetration.In addition,the experiment relationship between the blow counts N_(10) and the relative density D_r is built by simple statistics.A light penetration test method is put forward to test the coarse-sand relative density at abutment back of bridge-culvert back sand filling. |
