Abstract:This paper presents composite injection method, and it consists of static pressure injection method and high-pressure whirl injection method sequence in time. The composite method has all the advantages of the two individual injection methods and eliminates the disadvantages of them. It also increases the possibility of success and the range of subgrade reinforcement. Its effect is very good for the reinforcement of subgrade to many old buildings and new buildings which have problems in their subgrade.

Abstract:After analyses on alternatives of deep foundation pit for UNION HOSPITAL SURGERY WARD BUILDING, the alternative of using brake truss as retaining structure for foundation pit with ring beam bracing was put forward. This retaining structure has great stiffness, little deformation and reasonable fore distribution. It can well control the displacement around the supporting piles and make pit excavation convenient.

Abstract:为保证地下连续墙的施工质量，发挥其应有的设计功能，对其质量的检测是十分必要的，而传统的钻孔、开挖、围井等方法，不但破坏墙体影响其功能的正常发挥，而且费时费力，局限性很大，利用地球物理探测技术进行地下连续墙的无损检测已成为工程质量检查的必然发展方向。详细说明了地下连续墙无损检测技术的原理、实测方法和数据处理过程及其应用效果，并就有关问题进行了探讨。

Abstract:在天津市地铁老厢体改造过程中，由于厢体底板埋深大，地下水水位埋深浅，在破除厢体底板后就有很大的水位差，地下水会从厢体底板破坏处涌出，给基坑内施工及厢体底部止水造成很大的困难。鉴于该工程施工条件差、情况特殊、施工精度要求高的特点，通过查询有关数据以及现场实际条件，设计一套可行的施工工艺，成功地完成了厢体底板下的止水工作。

Abstract:Sand control has important meanings to sanding formation. It can affect the exploitation directly. Sand control technology today includes four sorts: mechanical sand control, chemical sand control, arch sand control and coking sand control. But mechanical are applied the most abroad, the principle is blocking sand in physical way. It was used from the early 20 century, with the development of new technology and new material, mechanical sand control are promoted greatly. From the 1990s, many kinds of new sand control method are used in oil field, and get satisfying result.

Abstract:Following the theory of underground structure design and Drucker-Prager standard for rock yield,the wall rock stability of a highway tunnel in Guangxi was analyzed by finite element method, taking self bearing capacity of wall rock into account. The effects of excavation methods and sequences on wall rock stability were analyzed. The wall rock excavation process was simulated. The displacement, stress condition, and the change pattern of displacement and stress in time were determined, providing the foundation for selection of excavation methods and supporting time in tunnel construction.
