Some geotechnical problems discovered in engineering practice

在简略介绍了在工程实践中发现的几个土工问题后,叙述了这些问题的发现和研究过程,采用的研究方法以及进行这类工作的体会。这几个问题是:土坝护坡的隆起;输水洞壁的黏结物;土坝灌浆和(三轴)试样在卸荷时的体缩。

Several geotechnical problems were uncovered during engineering practice and these problems are briefly described in the paper. These problems are： bulges on a hand placed slope protection of an earth dam; soil-like deposits on the inner wall of a conduit passing through an earth dam; fracture of grouting when sealing the cohesive fill of an earth dam; and volume contraction of a soil specimen in a consolidated and drained triaxial cell subjected to axial unloading. In the paper, a presentation is given on the research methodology to be adopted and the process of investigations for the aforementioned geotechnical problems.
