The active criterion strictly stipulates spacing of exploration point and lay gradient of bearing stratum for end-bearing pile,but in the site where the rock is for bearing stratum,the lay gradient of rock undulates in large extent due to sedimentary circumstance and geologic structure.
现行的标准对端承桩的勘探点间距与持力层层面坡度的变化情况做出了严格的规定,但在以基岩作为桩端持力层的场地,由于受沉积环境与地质构造的影响,持力岩层的层面变化较大,如果严格按打入桩的要求来控制,则勘察工作量将大幅增加,而且也很难做到。
With the theory of sequence stratigraphy and seismic stratigraphy, it analyses the various types of lithologic-stratigraphic traps, their occurrence conditions and the exploration difficulty, and also proposes the exploration thinking that builds in the basement of finding o.
