关于在软土基础上水工建筑物的地基资料的搜集,由于各地的地质条件和工作条件不同,不可能有一定的规律。现就个人所接触到的有关钻探、试验及设计等工作中的一些体会,提出初步意见以供讨论。一、钻孔布置水工建筑物一般基础面积很大,设计荷载很大,因此附加府力在土层中扩散也很深。同时,为了满足防渗和施工排水的要求,必须了解地基中水文地质的情况。因此,水工建筑物地基钻探的目的和性质有房屋建筑基本上是不同的。在布置钻孔中,必须充分掌握这一特性。 1.布置钻孔与规划及查勘的关系:在布孔以前座该深入了解规划的意图,配合查勘进行初步浅层(约
With regard to the collection of foundation data of hydraulic structures on the basis of soft soil, due to different geological conditions and working conditions in different places, it is impossible to have certain laws. We are now discussing some of the personal experiences we have encountered in drilling, testing and designing. First, the layout of hydraulic structures hydraulic general building a large area, the design load is large, so the additional force in the soil is also very deep diffusion. At the same time, in order to meet the requirements of seepage prevention and construction drainage, it is necessary to understand the hydrogeology in the foundation. Therefore, the purpose and nature of the foundation drilling of hydraulic structures are basically different from the building construction. In the arrangement of drilling, we must fully grasp this feature. 1. Arrangement of the relationship between drilling and planning and survey: In front of the cloth hole, this in-depth understanding of the plan’s intention, in conjunction with the survey conducted a preliminary shallow (about
