本文系根据1956年6月8日苏联部長会議国家建設委員会批准的“在下沉性大孔土上建筑物和工業構筑物設計及施工标准及技术規范”(-137-56)編写的。主要內容为設計工業企業室內外上下水設施,計兩个部分:第一部分为文字,第二部分为圖紙。第一章一般要求第一节大孔土简论大孔土是一种粘土質土壤,在天然狀态下,具有肉眼看得见的空隙,其大小远远超过組成土壤結構的微粒。大孔土浸水后具有下沉的性能,即由于天然結構本身的压縮而变形。大孔土浸水时的压縮和下沉,对于土壤在天然湿度下由于加負荷而發生下沉来說,是一种附加沉陷。
This article was prepared on the basis of the “Standards and Technical Specifications for the Design and Construction of Buildings and Industrial Structures on Subsiding Macroporous Earthwork” (-137-56) approved by the State Council of the Soviet Ministerial Conference on June 8, 1956. . The main content is the design of indoor and outdoor water facilities for industrial enterprises. There are two parts: the first part is the text, and the second part is the drawings. Chapter 1 General Requirements Section I. Macroporous Soils Macroporous soils are clayy soils. In the natural state, they have visible voids that are much larger than the particles that make up the soil structure. After the macroporous soil is immersed in water, it has a sinking property, that is, it deforms due to the compression of the natural structure itself. The compression and subsidence of macroporous soils when they are submerged in water is an additional subsidence to subsidence of the soil due to the loading under natural humidity.
