In the early stage of drilling, we can first understand possible distribution of the soil layers based on the existing drilling data. However, if the existing drilling information is not enough, it is very subjective to determine proper borehole numbers following only the construction codes. In this study, the authors explored the spatial variability of the soil formation parameters of three construction sites in northern Taiwan. The number of drill holes in construction A, B and C is about 50, about 30 and about 20, respectively. According to the borehole data, the semi-variogram corresponding to the soil parameters at each site was described by the semi-variogram functions. From the semi-variogram the range can be obtained and deemed as the range of influence., Therefore, the range can be compared to the existing spacing between the boreholes. If the range is less than the existing borehole spacing, it is regarded that the spacing may be reduced in order to obtain a more representative soil boring information On the contrary, if the spacing is less than the range under a given soil parameter, this indicated that the spacing may be proper to obtain representative soil parameters. 黃文昭 2018 學位論文 ; thesis 121 zh-TW |
