Representation Method

The effects of the first four statistical moments defining the statistical characteristic of elastic modulus on the probabilistic foundation settlement are investigated in this study. By combining the Hermite probability model and spectral representation method, a method to simulate nonGaussian homogenous fields based on the first four statistical moments is proposed. Linear elastic finite element models are employed to study the total settlement and the differential settlement of a shallow foundation. Probabilistic measurements of total–differential settlement obtained by the Monte Carlo simulations are presented. For the cases considered, the effects of skewness and kurtosis defining the probabilistic characteristic of elastic modulus on the total–differential settlement of a probabilistic foundation are illustrated. The computed results show that the value of skewness has a more significant effect on the probabilistic foundation settlement than kurtosis, and the case with the smallest skewness is observed as the most critical one.

The Impact

The large-size flexible shallow foundation （LFSF） can not be designed fully in accordance with the shallow foundation design specification, for there are differences between LFSF and traditional shallow foundation. Taking the foundation project of Shenzhen Mawan port for example, considering the interaction between foundation and ground base and adopting a non-linear foundation model, the impact of foundation parameters and load conditions on basal pressure and foundation settlement were simulated to value adoption of the height-width ratio by finite element method. Analysis showed that soil physical parameters of elastic modulus, Poisson's ratio had great impacts on basal pressure and foundation settlement, and the accuracy of these parameters should be ensure in modeling. However the effects of expansion angle and cohesion were relatively small. The values of expansion angle and cohesion can refer to design specification. Foundation of this type mainly focus on flexural design.

A Construction of buildings on the beach is needed to provide facilities and infrastructure. An analysis of bearing capacity and foundation settlement for building construction is necessary to avoid structural failure. This study analyzed bearing capacity and foundation settlement on the East coast of Bangka Regency, Bangka Belitung Island Province, including Tikus Beach, Takari Beach and Karang Mas Air Anyir Beach, based on field data from Cone Penetration Test (CPT). Result showed that the level of soil consistency, bearing capacity, and foundation settlement can be analyzed by combining the structural loads for the 1 to 5 floor buildings. Bearing capacity of shallow foundation was calculated using the Meyerhof (1976) method, whereas the deep foundation is using the Meyerhof (1956) method. Settlement of shallow foundation was calculated using the Steinbrenner (1934) method, whereas the deep foundation is using the Vesic (1970) method. This study found the soil consistency levels at three locations had the range from medium to hard level. The analysis of foundation bearing capacity showed that the greater of soil bearing capacity, the smaller of foundation dimensions. The greater the load that must be held by the foundation, the greater the size of the foundation needed to withstand it. The analysis of the settlement showed that the smaller of the soil bearing capacity, the greater of settlement. The greater the load that must be withheld by the foundation, the foundation settlement will greater.

Abstract An analysis is presented for the action of individual tire tread elements on polished sections of pavement covered by thin fluid films. Tread element flexibility, wheel slip, and time-dependent loading are incorporated. The effect of the lateral expansion of tread elements on groove closure is also studied.
