随着科学技术和经济建设发展的需要,在软弱地基上建造建筑物的情况越来越多,采用桩基作为建筑物的基础也就日趋普遍,尤其在现代施工技术、条件不断提高的情况下,桩的设计长度与荷载也越来越大,而且在很多情况下,桩端达到岩层或不可压缩土层,附近还有大面积填土、堆料场等,由此可能产生负摩阻力。本文主要讨论堆料场对其附近的桩引起的负摩阻力。 With the development of science and technology and economic construction, there are more and more cases of building buildings on soft foundations. It is also increasingly common to adopt pile foundations as the foundation of buildings. Especially in the case of modern construction technology, conditions are constantly rising , The design length and load of the pile are also increasing, and in many cases, the pile end reaches the rock or incompressible soil, there is a large area near the fill, stockyard, etc., which may produce negative friction. This paper mainly discusses the negative friction caused by the pile yard near the pile.
