In order to analysis post-cast concrete strip influence to the pile-raft foundation, it has been taken to developed C++ program that is Poulos displacement solution calculating pile-soil stiffness and thick plank theory analyzing raft stiffness. Taking a frame and shear wall structure for example, it has been calculated to pile-raft foundation whether setting up post-cast strip or not that is foundation settlement, moment and so on. Results indicate that post-cast concrete strip is minutely influence to the pile foundation displacement and moment and not the control factor to this kind of pile foundation’s design. It gives some good references to similar structure analysis and can instruct this kind of pile-raft foundation design and construction

Due to the physical properties of the soil between piles discrete，thus，composite pile foundation 's bearing capacity exists some uncertainty. So far, the study of the reliability of composite pile foundation is transform from the allowable stress method to the probability limit state design method. That is to say probability definite value design method. Therefor , determine the resistance subentry coefficient become the key of the design method. This paper introduces the significance of the subentry coefficient and the subentry coefficient of the composite pile foundation. Through the calculation of engineering examples, this article give the values of the subentry coefficient and provide a reference for the design of composite pile later.

Integrated Optimization Design

The aerodynamic performance, structural strength and wheel weight are three important factors in the design process of the radial turbine. This paper presents an investigation on these aspects and develops an optimization design approach for radial turbine with consideration of the three factors. The aerodynamic design for the turbine wheel with inlet diameter of 230mm for 100kW-class microturbine unit is carried out firstly as the original design. Then, the cylinder parabolic geometrical design method is applied to the wheel modeling and structural design, but the maximum stress predicted by Finite Element Analysis greatly exceeds the yield limit of material. Furthermore, the wheel weight is above 7.2kg thus bringing some critical difficulties for bearing design and turbine operation. Therefore, an integrated optimization design method for radial turbine is studied and developed in this paper with focus on the wheel design. Meridional profiles and shape lines of turbine wheel are optimized with consideration of the whole wheel weight. Main structural modeling parameters are reselected to reduce the wheel weight. Trade-off between aerodynamic performance and strength performance is highly emphasized during the optimization design. The results show that the optimized turbine wheel gets high aerodynamic performance and acceptable stress distribution with the weight less than 3.8kg.
