3、tection of deep foundation pits in narrow urban areas on various construction projects during the reconstruction.Keywords: retaining wall, anchor, trials.There are various types of fencing when deep foundation pits are o

4、rganized. The most widespread one is pile-beam-type fencing (so-called Berlin support). You can see such structure in Fig. 1. This fencing was used in Minsk in Shornaya street. Such structure provides steadiness through

5、the organized inclined earthfill without anchorage from one side of the pit and through the possibility of shifting of the fencing in the direction of the excavation from the other side of the foundation pit.Disadvantage

6、s of pile-beam-type fencing:1. Heavy expenses of steel section in short supply for installation of support.2. Heavy expenses of timber, which is used for horizontal sheeting between supports.3. Adverse dynamic influence

7、on surrounding buildings during the driving double tees. The driving double tees into boreholes helps to reduce this influence.Fig. 1. Pile-beam-type fencing without anchors of deep foundation pitFencing in the form of t

8、rench or pile walls haven’t got disadvantages mentioned above. Moreover, such fencing can combine load-bearing and antifiltering functions during the embedding in aquifuge.If the foundation pit is more than 7 meters deep

9、 the steadiness of trench walls is provided by setting-up of one or several tiers of strut rails or anchors for perception of horizontal stress of soil and for perception of vertical load. This makes it possible to reduc
