To control the deformation disaster and explore the effective in-situ evaluation method of filling in the Loess Plateau of China, the laboratory tests and cone penetration test (CPT), dynamic penetration test (DPT), standard penetration test (SPT) were carried out for a case of filling with large area. The research was performed based on data distribution, non-uniformity evaluation, correlation and sensitivity analysis. The results are as follows: (1) the filling filled by layered compaction still has non-uniformity. The distribution of CPT tip resistance is consistent with collapsibility coefficient and obeys logarithmic normal distribution. The distribution of CPT side friction and SPT hammer number are consistent with moisture content, void ratio and dry density and obey normal distribution. The distribution of DPT hammer number does not correspond to any soil properties index. The CPT also has the advantages to reflect layered compaction characteristics along filling depth and distinguish the boundary between filling and undisturbed soil. (2) Three test methods can all reflect the non-uniformity of soil properties in depth direction. However, for the horizontal direction, the CPT results can best reflect non-uniformity of actual collapse deformation, followed by SPT and DPT is the worst. (3) For the testing of filling compaction state, CPT tip resistance and SPT have good mathematical correlation, and the sensitivity of CPT tip resistance is significantly higher than other methods. For the testing of filling collapse deformation capacity, the CPT tip resistance, DPT and SPT all have good correlation and sensitivity. So CPT tip resistance has the best cooperation between correlation and sensitivity. (4) The CPT (especially tip resistance part) can be effectively applied to the properties evaluation of silty loess filling. The tip resistance to void ratio and collapsibility coefficient follow the exponential function and logarithmic function respectively.

为控制我国黄土高原充填体的变形灾害，探索有效的原位评价方法，开展了室内试验和锥入试验（CPT）、动力贯入试验（DPT）、标准贯入试验（SPT）对于大面积填充的情况。该研究基于数据分布、非均匀性评估、相关性和敏感性分析进行。结果如下：（1）分层压实填充的填料仍存在不均匀性。CPT 尖端电阻的分布与塌陷系数一致，服从对数正态分布。CPT侧摩擦和SPT锤数分布与含水率、空隙率和干密度一致，服从正态分布。DPT 锤数的分布不对应任何土壤性质指标。CPT 还具有沿填充深度反映分层压实特性并区分填充和未扰动土壤之间的边界的优点。(2) 三种试验方法均能反映深度方向土体性质的不均匀性。然而，对于水平方向，CPT结果最能反映实际坍塌变形的不均匀性，其次是SPT，DPT最差。(3)对于充填压实状态的测试，CPT尖端电阻与SPT具有良好的数学相关性，CPT尖端电阻的灵敏度明显高于其他方法。对于充填塌陷变形能力的测试，CPT 尖端阻力、DPT 和 SPT 都具有良好的相关性和敏感性。所以CPT尖端电阻在相关性和灵敏度之间具有最好的配合。(4) CPT（尤其是尖端阻力部分）可以有效地应用于粉质黄土充填物的性质评价。尖端阻力空隙率和塌陷系数分别遵循指数函数和对数函数。
