- 摘要：Some conclusions were drawn from two groups of in-site tests on concrete pile composite foundations. In the tests, it was found that the pressure under the rigid loading slab is different, in which the pressure under the center of the slab is the less and under the edge of the slab is the biggest. The pile-soil stress ratio is not a constant; it increases with the adding of the load. Most of the pile-soil ratio vary from 9 to 13 in these tests and the load that the piles share can be more than seventy percent of the whole load. It was proved that the bearing capacity of the concrete pile composite foundation is high with a little settlement, so it will be used more and more in the future.542|8|0更新时间：2023-11-28

- 摘要：The nutrition for the bacteria in the standing storage water changes gradually from plentiful to deficiency. The bacteria adopt a series of self-organization to adapt the sub-nutrition environment with forming the following characteristics: 1) Decreasing the metabolic level, slowing down the breeding velocity; 2) Enlarging the utilization ability for different kind of material; 3) Reducing the bulk and increasing the specific area; 4) Presenting in the form of bio-film, 5) Strengthening the resistance. To ensure the water quality security of long-term storage water, these characteristics should be paid attention to when solving the issue of water quality deterioration for the storage water.574|7|0更新时间：2023-11-28

The Effect of Water-Cement Ratio on the Plastic Shrinkage Cracking of Lightweight Aggregate Concrete
摘要：In this paper, the characteristic of the plastic shrinkage cracking of the lightweight aggregate concrete (LWAC) was studied under the condition of prescribed quantity of cement and aggregate and was compared with that of the normal aggregate concrete (NC) with the same proportion of materials for the LWAC. The results suggested that the water evaporation quantity in the concrete became larger with the increase of w/c, and water evaporation velocity reached maximum value around two hours. When the water-cement ratio was low, the area of the plastic shrinkage cracking of LWAC was large and when w/c was 0.40, the area reached the maximum value and then became smaller with the increase of w/c.825|817|0更新时间：2023-11-28 - 摘要：There is a popular opinion that SBS can improve both high and low temperature performance of base bitumen. In this study, four kinds of SBS are used to modify three kinds of common domestic bitumen and one kind of foreign one; some final products of SBS modified bitumen are obtained. The rheological properties of SBS modified bitumen after RTFO/PAV are studied by using bending beam Rheometer (BBR), which is one of the test methods of SHRP. The results indicate that the low temperature grade of SBS modified bitumen made by physical method is at the same level as that of base bitumen. In other words, the SBS modification effect on low temperature anti-cracking performance of base bitumen still deserves to study from the meaning of rheology.594|871|0更新时间：2023-11-28
- 摘要：It is the major way to form a civil engineering contract by means of bidding and tendering passing through the following steps as: tendering, bidding, bid opening, evaluation, acceptance and contract signing. The legal nature of the bid is an invitation to offer. The bid has certain legal binding which is different from the ordinary invitation to offer. The legal nature of the tendering is an order, which is sent to the inviter by the bidder. The letter of acceptance takes effect when it is issued and meanwhile the civil engineering contract is formed.574|811|0更新时间：2023-11-28

- 摘要：In the construction projects, the contract, which is the most important behavior norm, determines the rights and responsibilities of client and contractor. All engineering activities aim at implementing and carrying out the articles of the contract. However, as the key component of the contract, the type of contract price determines the distribution mode of most of the engineering risk between client and contractor. In this paper, the most popular types of contract price used in the international construction projects are introduced. The advantages and disadvantages of each type and the distribution mode of the engineering risk between client and contractor are analyzed. At the end, some advice are given to the clients that they should choose the proper type of contract price and have innovation according to the characteristics of certain project and the situation of themselves.773|717|0更新时间：2023-11-28

- 摘要：Construction site is noted for its dense population, high mobility of construction workers, hard working and poor living conditions. Therefore, during the SARS spreading period, the local government put the construction site into the strictly control list in view of the outbreak of SARS. Some contractors were punished because of their poor measures taken for controlling the SARS. Under the SARS attack, for the construction firm, it is necessary to have good site environment control. The environment benefit and economical benefit due to site environment management have been elaborated in this paper. The legal duty of the contractor is also explored in view of related laws and regulations. The management framework and site environment practice are discussed in detail.733|1014|0更新时间：2023-11-28
- 摘要：The firm governing is a structure with a board as its core, and its goal is to guard the interests and rights of the shareholders and related people thru supervising the management under the condition of firm's ownership and management separation. So, it is very important to know what the board structure is and whether it can work properly. Thru constructing board model and conducting theoretical and empirical analysis, in this paper, a best model of the board including the shareholders, managers and outsiders is proposed. In order to improve the efficiency of the board, attention should be paid to the following: composition of the board, separation of board director and general manager and the incentive scheme to outside board members.1257|7|0更新时间：2023-11-28
