Diaphragm wall-soil-cap interaction in rectangular-closed- diaphragm-wall bridge foundations

Hua WEN, Qiangong CHENG, Fanchao MENG, Xiaodong CHEN

Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 1, Pages 93-100 doi: 10.1007/s11709-009-0015-4

Abstract: Diaphragm wall-soil-cap interaction was studied using a model test.It was observed that the distribution of soil resistance under the cap is not homogeneous.The distribution of soil resistance under the cap will be more uniform, if the sectional area of soilThe load shearing percentage of soil resistance under the cap is 10%-20%.It is unreasonable to ignore the effects of the cap and the soil resistance under the cap in bearing

The Supply Chain Contract Design under Cap-and-Trade Mechanism with Free Riding

Fu-qiang Wang,Jun Liu

Frontiers of Engineering Management 2015, Volume 2, Issue 3, Pages 277-286 doi: 10.15302/J-FEM-2015049

Abstract: This paper studies the influence of free riding on enterprise product pricing and carbon emissions reduction investment, as well as the contract design to achieve supply chain coordination under the carbon trading mechanism. First, we discuss the situation where carbon emissions reduction investment affects the product price and income. It demonstrates that the optimal investment of the upstream manufacturer increases with the degree of the free riding of the downstream manufacturer. The upstream manufacturer can improve their carbon reduction investment and the whole supply chain achieves Pareto improvement when the investment cost sharing contract is introduced. Nevertheless, under the cost-sharing contract the optimal investment of the decentralized supply chain is still lower than that of the centralized supply chain, and only in some particular cases can the two types of supply chain achieve equal total profits. Then, we preliminarily explore the situation where the product price and income is influenced by carbon emissions reduction investment. The consequences indicate that the optimal investment of the upstream manufacturers in this situation is less than the former one’s, and the transfer payment mechanism is able to improve the level of the supply chain overall carbon emissions-reduction. Moreover, compared to the former situation, the effects of free riding of the downstream manufacturer are even more serious. The conclusions can provide some intellectual support for manufacturing enterprises to make reasonable emissions reduction strategies and coordinate the supply chain existing in free riding.
