Brown gray clay 90-10o9010o9510510o11O Figure 5 a combination of Figure 9 and Table 3,[link widoczny dla zalogowanych], Table 4, with the flat dilatometer test calculation of the Shanghai area of shallow foundation bearing capacity of the soil analysis and evaluation of calculation accuracy of the formula is as follows: (1) from Table 3 can be seen,[link widoczny dla zalogowanych], with the flat dilatometer test to determine the bearing capacity to determine the scope and use of other methods consistent with the scope of foundation bearing capacity; (2) can be seen from Table 4,[link widoczny dla zalogowanych], the maximum frequency range of distribution,[link widoczny dla zalogowanych], the side with the flat shovel calculate the bearing capacity expansion test and other methods used basically the same to determine the bearing capacity; (3) The layer of brown clay ② and ② one layer of gray silt,[link widoczny dla zalogowanych], flat shovel modulus checking out the longer-range much reflected in the distribution (1) The analysis shows that can be used flat dilatometer test bearing capacity calculations, the formula shown in Table 1; (2) comparative analysis show that the empirical formula derived to meet the accuracy requirements; (3 ) In this paper, Shanghai, with the flat dilatometer test experiences bearing capacity calculation formula, the formula's applicability in other areas further research needs to be done. (4) In order to better summed up the law, the proposed geotechnical investigation in the future, the more increase the flat dilatometer test project.
