摘要
本文是结合干船坞规范编制中的柱基问题,在调查研究和模型试验的基础上,针对船坞底板下桩基的抗浮问题,提出的一份研究报告。我们通过同一种土层上的单桩与群桩,而群桩中又通过不同入土深度和不同桩数等方面进行了对比性的模型试验。通过分析,对抗拔单桩和群桩的破坏机理、承载力和优化的入土深度,都有了一些新的规律性的认识。研究成果已列入我国干船坞设计规范(1985),并可供其他海上和陆上的桩基工程按抗拔设计时参考。
Based on investigation and model tests combined-Withpile foundation on code ompilation of drydocks, we present this report to give informations against uplift cressure of piles beneath floor of drydockolna same kindof soil,we havegot comparetire tests results with single pile and pile group, and the latter was performed at different spaclngs.different embedded depths and different number of piles in the goup. Having analyzed through the results, there are some new understanding of regularity about failure mechanism and uplifting capacity of singlepileandpile group, as well as optimum embedded depth of pile foundation. The results of research approach to measured values of full-scale and model tests at home and abroad, it has been placed tnto the Design Code of Drydock in China(1985), and can give a reference to design of pile foundation at sea and on land under uplift loading.
