You will need to create a custom variable RouteValueDictionaryto go to Html.ActionLink. Try something like this:

<% 
     var rvd = new RouteValueDictionary(ViewContext.RouteData.Values);
     foreach (string key in Request.QueryString.Keys )
     {
         rvd[key]=Request.QueryString[key];
     } 
     rvd["MyParam"] = "WhateverValue";
     Response.Write(Html.ActionLink("Link Text", "Action", rvd));
%>
