This paper introduced the construction technology of pile patching,caps and middle cross beam reinforcement of the International Trade Bridge in Beijing.The pile patching method is applying pile reinforcement to bridge pier foundation,which means building a 1.5 m diameter pile in each north and south side of the bridge original cap.Building new caps is to spray concrete in steel net,set bolt anchor on the wall of foundation pit based on slope excavation,lift and install the girder for flanged beam lifting,and band reinforcement bar and cast concrete at the bottom of original cap.Reinforcing middle cross beam is to add two steel piles on both sides of the bridge piers in order to support steel cap beam which can support cross beams with adjustable force basin rubber pedestal and convert single-point-support to three-points-support so as to improve the beam force condition,and reinforce the steel beams by pasting the steel plates so as to enhance the beam shear capacity.

At the basis of analysis on influencing factors of collapsibility of loessal foundation,it is subjected that the collapsibile deformation should be thought of as a system that many factors worked and influenced together,especially a grey system..Thus the grey incidence analysis method can be applied to collapsibility of loessal foundation.and it is cheerful that the method works so well that some useful results could be attained according to the grey incidence analysis on influencing factors of collapsibility of loessal foundation,results indicat that the void ratio is the superior and steadily influencing factor of collapsibility at all events and other influencing factors will have some different degree of influence.The paper expounds some influencing factors of collapsibility and helps to think correctly some influencing factors in setting up the model of collapsibility.
