在国家基本建设中,岩土工程占有重要的地位。有效地使用这门工程技术,可以减少工程量,降低造价与缩短工期。因此进一步开展这门工程技术的研究,将对四化建设起到重要的作用。 绝大多数的工程建筑物如房屋、桥梁、铁路、公路、机场等等都是建筑在土基上的;也有一些建筑物如挡土墙、水闸、隧道、管道等等都是埋置在土基中的;更有一些建筑物如堤、坝等等本身是用土料筑成的。在作这些土基与土工建筑物构设计与施工时,土料工程特性如抗剪强度,应力与应变关系,渗透性等的测定,以及如何在作土体的变形与稳定计算中选用适当的土料工程特性指标是土力学及基础工程这门技术科学中最重要的研究课题。 本文将分两节来阐述笔者对这个课题研究动向的一些不成熟看法,即①土工试验,②数值计算与模型试验,提请批评指正。
In the country’s basic construction, geotechnical engineering occupies an important position. The effective use of this engineering technology can reduce the amount of work, reduce the cost and shorten the construction period. Therefore, further research on this engineering technology will play an important role in the construction of the four modernizations. The vast majority of engineering buildings such as houses, bridges, railways, highways, and airports are all built on soil foundations; there are also buildings such as retaining walls, sluice gates, tunnels, pipelines, etc. that are buried in soil. In the base; more buildings such as embankments, dams, etc. are built with earth. During the design and construction of these soil-based and geotechnical building structures, the properties of earth materials such as shear strength, stress-strain relationship, permeability, etc., as well as how to select suitable soil deformation and stability calculations Soil engineering performance indicators are the most important research topics in the field of soil mechanics and basic engineering. This article will be divided into two sections to describe some of the immaturity of the author’s research trends in this topic, namely 1 geotechnical test, 2 numerical calculations and model tests, to draw criticism and correction.
