黄河大堤自从锥探以来,已经获得很大成效。但据我所见,大堤仍有以下弱点,尚须采取有效措施根除:(1)小的獾洞、鼠穴、蛇窝等随着大堤的加高培厚逐渐上钻、扩大。(2)由于大堤逐年加高培厚,新旧不易结合,弱点逐年增多,尤其红胶土,修提时夯实得本来很坚固,但一干即裂开许多大小不同的裂缝。这些裂缝在锥探时锥不出,但灌泥浆时有的十车廿车的泥浆还灌不满。(3)目前某些堤段坟、井
The Yellow River embankment has gained great success since its cone exploration. However, as far as I can see, there are still some weaknesses in the embankment, and effective measures must still be taken to eradicate them: (1) Small Badger’s Cave, Rat Cave, Snake’s Nest, etc. are gradually drilled and enlarged as the levee is raised. (2) As the levee increases year by year thicker, the old and the new are not easy to combine, the weakness increases year by year. In particular, the red clay soil is solidly built when it is repaired, but it cracks a lot of cracks of different sizes once dry. These cracks did not cone out during cone exploration, but some of the mud in the 20-car was irrigated at the time of grouting. (3) At present, some embankments, wells
