Settlement deformation in the foundation with miscellaneous fill and soft soil was typically calculated by summing up the settlement in each individual layer. However, this calculation method did not involve settlement deformation by embedding miscellaneous fill particles into soft soils under external loads, thus inducing significant settlement prediction error. To solve this problem, a laboratory testing device was developed to study the mutual embedding for specimens with different miscellaneous fill particle sizes, external loads, and particle materials. Testing results indicate that a larger particle size and subsequently the smaller specific surface resulted in greater mutual embedding settlement due to the smaller resistance. In addition, higher external loads and smaller interface friction both induced larger settlement. Based on these results, a theoretical calculation equation of settlement due to the mutual embedding of miscellaneous fill and soft soil was proposed. The calculated settlements were found to be well matching with the experimental results.

杂填土与软土地基相互嵌入引起沉降的试验研究。

通常通过汇总每个单独层的沉降量来计算具有各种填充和软土的地基中的沉降变形。但是，该计算方法不涉及通过在外部载荷下将其他填充颗粒嵌入软土中而引起的沉降变形，从而引起较大的沉降预测误差。为了解决这个问题，开发了一种实验室测试设备，以研究具有不同填充颗粒大小，外部载荷和颗粒材料的标本的相互嵌入。测试结果表明，由于电阻较小，较大的粒径和较小的比表面积会导致更大的相互嵌入沉降。另外，较高的外部载荷和较小的界面摩擦力都引起较大的沉降。在此基础上，提出了杂土与软土相互埋设的沉降理论计算公式。发现计算的沉降与实验结果非常吻合。
